I updated our dependencies like binrw to 0.15, which is pretty nice as
that means we no longer depend on Syn 1.x. I also finally upgraded to
bitflags 2.x, which doesn't really mean anything except we're on
better supported version.
Additionally, I removed some bitrotten code that no longer compiles.
This was mostly benchmark stuff, but since I don't actively keep track
of that I felt it was better to remove it. I can always add it back once
I'm ready to tackle that again.
Now it reads much more of the index file format, and tries to handle
index1/index2 differences more opaquely. I'm not yet happy with the API, it
needs a bit more work.
This removes the dependency of the Havok SDK or getting the decompiled
skeleton files from TexTools or some other place. Code courtesy of
FFXIVTools. The other two ways of reading skeletons (SKEL and Packfile)
are removed which gets rid of two dependencies.
