tilequant 241101-qualetize

Pre-built binary of the soft-reboot is now available.

I decided to soft-reboot the project, under the name "Qualetize". Processing is now much, /much/ better by all metrics, and there is support for much more features (still restricted to BMP files, though).

Decided to pick up this project a bit while taking a break from another project I'm working on.

Much improvement has been achieved.

Aside from quality improvements, the tool now supports passing arguments (eg. tile size, dither type, etc.) via the command line.

Bugs were fixed (quantization is now consistently very fast), quality was improved (working entirely within YCoCg mode), quantization was improved a LOT more.

Aside from some pathological cases (eg. mostly single-colour images), this version should run a lot faster. Also added ordered dithering.
