Alex Hall 6c90de4d62 (core) Switch excel import parsing from messytables+xlrd to openpyxl, and ignore empty rows ... Summary: Use openpyxl instead of messytables (which used xlrd internally) in import_xls.py. Skip empty rows since excel files can easily contain huge numbers of them. Drop support for xls files (which openpyxl doesn't support) in favour of the newer xlsx format. Fix some details relating to python virtualenvs and dependencies, as Jenkins was failing to find new Python dependencies. Test Plan: Mostly relying on existing tests. Updated various tests which referred to xls files instead of xlsx. Added a Python test for skipping empty rows.
