Added

- `--skip_empty`, `--threshold_empty`

Fixed

- Processing of grayscale and black-and-white images.

Changed

- Changed from `print()` to `logging`.

Added

- `--unsharp_mask`

Helps enhance fine textures.

Removed

- `--denoise_closing`

Reason: `--denoise_closing` was a morphological closing on the binary foreground mask.
Morphological *opening* on the binary foreground mask removes small segments by effectively replacing them with background.
Morphological *closing* might be useful for fine textures when applied to the actual image, but I don't see any benefit to applying it to the mask.

Changed

- Replaced `--global_palette` with `--local_palette` to make the global palette the default.

Added

- This changelog file
- Added a check for the existence of all input files so that the error is raised immediately and not halfway through processing.

Changed

- Switch from multi-processing to multi-threading for lower overhead, resulting in lower memory consumption and faster runtime.
- The location of the temporary folder for intermediate files has been changed to the current working location, so that it can be freely selected.

Added

- Multiprocessing
- Added `--jobs` flag
- Added `pipx` builds
- Added `--quality` flag
