Switch to faustwasm and reorganize

[ijc8]

Builds on #3. Instead of checking in copies of faustwasm and faust-ui into this repository, this PR creates package.json and lists them (along with CodeMirror 5, which is already copied on master) as npm dependencies, with the aim of decluttering the repo and simplifying maintenance.

WIP. Remaining tasks:

• Convert remaining scripts into ES modules so vite build works.
• Configure GitHub actions so that this will continue to work as a GitHub pages site.
• Finish testing.
• Update README with setup & build instructions.

Questions:

• What's the status of the faustlive-wasm stuff? The live version at https://fausteditor.grame.fr/faustlive-wasm.html seems to be broken.
• What's the status of _f4u$t, and how does it relate to the newer faust-ui?

[sletz]

• https://fausteditor.grame.fr/faustlive-wasm.html is fixed

• _f4u$t is related to the old SVG based GUI (developed by Mike Solomon in 2013). faust_ui is Shihong new GUI model, developed for Faust IDE. We can discuss if moving from f4u$t to faust_ui can be done in fausteditor also, so that to only use and maintain one GUI model for all projects.

I understand the package has to be built using npm right ? can you possibly complete the README to explain how to build ? Thanks.

Testing with npm run dev:

• configure running mode, polyphonic mode is working
• but "Save DSP control parameters state" and "Save DSP source" are not woking anymore, seems an issue with local storage ?

And npm run build produces a dist folder with missing CSS ? (ugly display)

BTW: I guess some files like mixer32.wasm and libfaust-wasm.data (part of faustwasm subproject AFAICS) are not needed in the repository anymore right ?
