Bug 11679: Add ODS as an export format for reports

This patch adds the ability to export the data generated by a report
into an Open Document spreadsheet file.

Test plan:
1/ Install the new dependency
2/ Verify you are able to generate an ods file from a
report result.

Tested with several reports and downloaded them as Open Document
Spreadsheet. Wors as expected.
