Add the numcodecs-wasm package

[juntyr]

• numcodecs-wasm is the root package for my https://numcodecs-wasm.readthedocs.io/en/latest/ project, which provides several compression algorithms compiled to WASM. numcodecs-wasm provides the extension module to run the compressors, while all other packages, e.g. numcodecs-wasm-sz3, are pure-Python packages that can be installed on-demand with micropip
• numcodecs-combinators is a helper package for writing meta-compressors with numcodecs
• numcodecs-observers is a meta-compressor for recording performance stats during compression, numcodecs-wasm hooks into it to provide an additional performance stat (an instruction count measured inside WASM)
• varint is required by numcodecs-combinators

Could you add tests?

Could you add tests?

Absolutely! The easiest way to test would likely be to use micropip to install (so importantly we wouldn't need to store the WASM file in this repo since it's hosted on PyPi) one of the actual codecs from PyPi and let that encode + decode some data, which exercises all code in numcodecs-wasm. Does that sound good?

I would prefer making no network requests in our unittest, but if there are no small enough codecs you can use for testing, then yes, that approach would be fine.
