Add VPM support

I used the VRChat package tool to convert the package, although this did give me problems since Dynamic Bone & FIK Scripts aren't linked and you can't create assets in the package folders. I have remedied this by using runtime types to do the Dynamic Bone & FIK stuff, and have made it so saving presets happens in the assets folder. I have tested saving and loading presets, as well as copying and removing components, but I am not very familiar with the entire tool since I personally only use it for copying components, so I haven't ran a complete test on everything. Please let me know if you encounter any bugs or want me to change anything
