This fixes #1645 and fixes #1655

- Breaking changes, change the data type for the `HeaderFooterOptions` structure fields `AlignWithMargins` and `ScaleWithDoc` as a pointer
- Fixed panic on `AutoFilter` by adding nil pointer guard for local sheet ID
- Allow dot character in the defined name, table name, or pivot table name
- Update the unit tests
