Adds basic glTF import (although right now it only imports back
positions) and fixes support for more of the vertex data that's
available to us. The MDL file isn't written back out yet either, it only
displays in the viewport.
Now the hashes are collected in a central database (location to be
improved) similar to FFXIV Explorer. This database needs to be generated
once and doesn't have to be regen every time Sagasu is opened like
before. This indexer currently is a separate program.
Also adds a feature to extract files from the file tree window.
The number of lods are now properly loaded from the model data, and race
is checked by checking for the existence of race-specific models (I
think this is the current best way?).
Also, magic_enum is added as a dependency for some enum magic involving
enumerating Race.
