Mafs no longer has a runtime dependency on gl-matrix-invert, gl-mat2, gl-mat3, or gl-mat4. It was only using one small function from that whole suite of packages, so it has now been inlined into Mafs' code directly. Less to download is always nice.
It also no longer depends on classnames.
Additionally, Mafs no longer depends on React ^16.8, instead depending on React >=16.8. From a real compatibility standpoint, it always worked with React 17, but just had a bad semver string (oops).
