WIP: 2023 update

[dndrks]

in preparing a 2023 update of the monome Max package, i remembered that we had this repo! i propose archiving https://github.com/monome/serialosc.maxpat, as its redundant to what's inside of the package + duplicates our maintenance efforts. either way, i'll use this PR as a way to float proposed changes along :)

i've migrated all the changes in https://github.com/monome/serialosc.maxpat/pull/3 to this PR, with one very notable exception -- i've renamed serialosc.maxpat + serialosc.js to monome-device.maxpat + monome-device.js. i think this helps with a few things:

• since serialosc.maxpat has been pretty widely proliferated and we want people using this heavily-modified version, the name difference is helpful to avoid situations like 'so i replace serialosc.maxpat with serialosc.maxpat and hope it's the right one?'
• a rename is also an opportunity for clarity, since this patcher is not the serialosc service itself, but just a wrapper for Max to communicate with grids + arcs (which in turn use serialosc)

i've also updated the included patchers:

• [x] all use monome-device.maxpat bpatchers
• [x] each has unique arguments / prefixes to avoid collisions
• [x] fixed continuously-printing errors from VST helpers
• [x] added UI switching for plug-in/MIDI selector
• [x] migrated the more recent version of returns
• [x] fixed broken image link + touched-up monome_intro.maxpat

---

TODO

• [x] edit the included studies
• [x] edit docs/grid-studies/index.md text to reflect the changes above
• [x] take new screenshots
• [x] build 256 versions of the included patchers (#1)
