Coloring: Split --scalars in two options, --scalar-coloring and `…

…--coloring-array`

 - Remove `--scalars, -s`
 - Introduce `--scalar-coloring, -s` option and corresponding libf3d option
 - Introduce `coloring-array` option and corresponding libf3d option
 - Update tests and configs
 - Add an `enable` boolean to the SetColoring API
 - Update API usage in window and interactor
 - Remove fully F3D_RESERVED* constants
