21624	Optimise images on github Windows builds	Stereo	team	"==== What steps will reproduce the problem?
1. Download a tested windows build from https://github.com/JOSM/josm/releases/tag/18303-tested
2. Extract the images from wherever it stores the jar
3. Look at image sizes

==== What is the expected result?

Images are already optimised

==== What happens instead?

The [https://github.com/JOSM/josm/blob/master/.github/workflows/ant.yml#L108 image optimisation] only gets run on the macOS runner because it uses the imageoptim macOS app.

Images should be optimised in the svn tree. This would provide optimised images for every build, let us try a variety of slow and efficient PNG tools that aren't in imageoptim like [https://github.com/jibsen/pngwolf-zopfli pngwolf-zopfli], and speed up build times.
