Implement Drawpile 2.1 animation import
Imports an ORA file and reconstitutes it like Drawpile 2.1 would have animated it. Fixed layers get turned into tracks with a single frame at the beginning, layers get put into groups and put on matching tracks. Usually an animation will have one such group and track, unless fixed layers are used in the middle, in which case they get split up into multiple tracks so that the layering works correctly. This doesn't check if the ORA file being imported actually came from Drawpile 2.1, since it doesn't matter for the functionality.
