[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.
