v2.1.0

This is a significant update, primarily centered on replacing MeshRelation with MeshGL, which accomplishes the goal of maintaining material properties across operations much better and with a simpler, more performant API. I'm not considering this a breaking change, as MeshRelation turned out to be broken enough that I doubt it was getting much use anyway. For the WASM build on npm, this is definitely a breaking change as we've updated its API more significantly and switched to an ES6 module. This brings us up from v1.0 to v2.1 to keep a consistent version from now on.
