This release is planned to be just for NPM, to address a potentially
problematic bug with Wasm SIMD decoding, as well as a number of smaller
bugs.

MeshoptDecoder:

Fix a rare vertex decoding bug when using Wasm SIMD, decoding vertex
encoding version 1 encoded using maximum level (3) on data that ends
up using xor+rotate encoding with the most significant bit set.

Fix a rare race condition when using useWorkers(1), decodeGltfBufferAsync
followed by useWorkers(0) where a delay in Wasm instantiation could
cause a request to never complete.

MeshoptSimplifier:

Fix compactMesh behavior for Uint16Array inputs that previously did
not remap the input index array correctly

Fix simplifyPoints behavior when vertex_colors or color_weight was not
specified; previously the output could have slightly worse quality
than optimal.

Add absent TypeScript binding for generatePositionRemap.

MeshoptEncoder:

Fix reorderMesh to flag Uint16Array inputs as invalid; these never
worked properly but would silently corrupt index data previously.

Fix encodeFilterExp to validate that the mode is one of the known
strings.

MeshoptClusterizer:

Fix computeMeshletBounds on empty inputs to return empty array.
