Implement Columns field of imported .gpl palettes. (#1025)

Browse source 
* Implement Columns field of imported .gpl palettes.

- Fixes Columns field being ignored when imported.
- _fill_imported_palette_with_colors is modified to accept an optional
   width parameter, which defaults to Palette.DEFAULT_WIDTH instead of
   a hard-coded 8.
- A maximum of width of 16384 is enforced to mitigate maliciously large
  values.

* Run gdformat.

* Run gdlint.

* Consume all whitespace between field and value.
