Re: [Csnd-dev] [EXTERNAL] Re: [Csnd-dev] New API - updates

FYI: I paired up with Hlodver today and we went through and updated
the newapi branch for WASM. Unit tests passed and I tested with my
live.csound.com site and it's working for me there for live coding.

(We did some examining of the build and are going to continue to look
at modernizing the wasm and browser code.)

Regarding the build artifacts, I think we'll need a PR opened up for
the branch before any workflows will run.
