[ADD] survey_xlsx_expand_multiple_choice, survey_xlsx_extra_fields

survey_xlsx_expand_multiple_choice: expand multiple_choice questions into
one Oui/Non column per option, and matrix questions into one column per
row (value = selected option). Relies on the extension hooks added to
survey_xlsx.

survey_xlsx_extra_fields: bridge (auto_install) with survey_extra_fields
that excludes 'file' question types from the XLSX export.

+This module improves the **Survey Results XLSX export** provided by
+``survey_xlsx`` for questions that can hold several answers.
+
+By default such questions are exported as a single column containing every
+selected value joined together, which is hard to analyse in a spreadsheet.
+This module splits them into dedicated columns:
+
+* **Multiple choice** questions (*multiple answers allowed*): one column per
+  possible answer, with ``Oui`` / ``Non`` as value.
+* **Matrix** questions: one column per matrix row, with the selected option
+  as value.
+
+.. warning::
+
+   This module relies on report extension hooks that are **not part of the
+   standard** ``survey_xlsx`` yet. They are introduced by this pull request:
+
+   https://github.com/elabore-coop/survey/pull/1
+
+   You must run a ``survey_xlsx`` that includes these hooks (the PR branch,
+   until it is merged upstream). Installed against a plain ``survey_xlsx``,
+   this module installs without error but the export **silently falls back**
+   to the default one-column-per-question behaviour.

+
+Usage
+=====
+
+Export the results of a survey as usual:
+
+#. Go to *Surveys* and open a survey.
+#. Print the *Survey Results XLSX* report.
+
+In the generated spreadsheet:
+
+* A multiple choice question ``Favorite colors`` with options *Red*, *Green*
+  and *Blue* produces three columns ``Favorite colors / Red``,
+  ``Favorite colors / Green`` and ``Favorite colors / Blue``, each containing
+  ``Oui`` or ``Non``.
+* A matrix question ``Satisfaction`` with rows *Dashboards* and *Customer
+  relationship* produces two columns ``Satisfaction / Dashboards`` and
+  ``Satisfaction / Customer relationship``, each containing the selected
+  option (e.g. *Not satisfied at all*).
+
+Other question types keep their standard single-column export.
+

+<p>This module improves the <strong>Survey Results XLSX export</strong> provided by
+<tt class="docutils literal">survey_xlsx</tt> for questions that can hold several answers.</p>
+<p>By default such questions are exported as a single column containing every
+selected value joined together, which is hard to analyse in a spreadsheet.
+This module splits them into dedicated columns:</p>
+<ul class="simple">
+<li><strong>Multiple choice</strong> questions (<em>multiple answers allowed</em>): one column per
+possible answer, with <tt class="docutils literal">Oui</tt> / <tt class="docutils literal">Non</tt> as value.</li>
+<li><strong>Matrix</strong> questions: one column per matrix row, with the selected option
+as value.</li>
+</ul>
+<div class="admonition warning">
+<p class="first admonition-title">Warning</p>
+<p>This module relies on report extension hooks that are <strong>not part of the
+standard</strong> <tt class="docutils literal">survey_xlsx</tt> yet. They are introduced by this pull request:</p>
+<p><a class="reference external" href="https://github.com/elabore-coop/survey/pull/1">https://github.com/elabore-coop/survey/pull/1</a></p>
+<p class="last">You must run a <tt class="docutils literal">survey_xlsx</tt> that includes these hooks (the PR branch,
+until it is merged upstream). Installed against a plain <tt class="docutils literal">survey_xlsx</tt>,
+this module installs without error but the export <strong>silently falls back</strong>
+to the default one-column-per-question behaviour.</p>

+This is a **bridge module** between ``survey_xlsx_expand_multiple_choice``
+and ``survey_extra_fields``.
+
+``survey_extra_fields`` adds a *File* question type, whose answers are
+uploaded attachments that cannot be represented in a spreadsheet cell. This
+module excludes those *File* questions from the **Survey Results XLSX
+export**: they get no column at all, instead of an unusable one.
+
+It installs automatically (``auto_install``) as soon as both
+``survey_xlsx_expand_multiple_choice`` and ``survey_extra_fields`` are
+installed, and is uninstalled when either of them is removed. There is
+nothing to configure.
+
+.. warning::
+
+   The exclusion is implemented through the report extension hooks provided
+   by ``survey_xlsx_expand_multiple_choice``, which itself relies on hooks
+   added to ``survey_xlsx`` by this pull request:
+
+   https://github.com/elabore-coop/survey/pull/1
+
+   Without those hooks, *File* questions are not filtered out of the export.

+<p>This is a <strong>bridge module</strong> between <tt class="docutils literal">survey_xlsx_expand_multiple_choice</tt>
+and <tt class="docutils literal">survey_extra_fields</tt>.</p>
+<p><tt class="docutils literal">survey_extra_fields</tt> adds a <em>File</em> question type, whose answers are
+uploaded attachments that cannot be represented in a spreadsheet cell. This
+module excludes those <em>File</em> questions from the <strong>Survey Results XLSX
+export</strong>: they get no column at all, instead of an unusable one.</p>
+<p>It installs automatically (<tt class="docutils literal">auto_install</tt>) as soon as both
+<tt class="docutils literal">survey_xlsx_expand_multiple_choice</tt> and <tt class="docutils literal">survey_extra_fields</tt> are
+installed, and is uninstalled when either of them is removed. There is
+nothing to configure.</p>
+<div class="admonition warning">
+<p class="first admonition-title">Warning</p>
+<p>The exclusion is implemented through the report extension hooks provided
+by <tt class="docutils literal">survey_xlsx_expand_multiple_choice</tt>, which itself relies on hooks
+added to <tt class="docutils literal">survey_xlsx</tt> by this pull request:</p>
+<p><a class="reference external" href="https://github.com/elabore-coop/survey/pull/1">https://github.com/elabore-coop/survey/pull/1</a></p>
+<p class="last">Without those hooks, <em>File</em> questions are not filtered out of the export.</p>
