v0.12.0

What's new

fastexcel 0.12.0 adds the following features:

• Support for excel tables
• A single dtype that will be used for all columns can now be specified when loading a sheet
• Sheets now have a visible attribute indicating wether they're visible, hidden or very hidden

Breaking changes

• The header_row parameter now represents the exact index of a row in a sheet. It is more explicit this way, but may break existing code relying on calamine's legacy row skipping behaviour (if empty rows were found at the beginning of the sheet)
