In previous versions, all FK bones(besides the part that directly drives the animation) were oriented upwards. I don't know if this was intentional in the current version, but some bones have a chaotic orientation. This causes problems for post-processing in other software, and I believe all bones should be oriented upwards.

I have restored this feature myself, and if this is considered make scene, I can create a pull request.

Previous versions ignored the bone rotation when the model was exported from koikatsu. In the new version the bones are like that because that's how they're actually oriented in-game.

I think it does make sense to rotate the bones upright when you click the export prep button, so please do!
