This is needed because if we want to ship to sublime, having the `pyo3/abi-*`
feature enabled will result in a wheel that needs the `python3.dll` (f****g windows)
which sublime does not ship. This works fine for Linux and Mac Os, but
for windows we will need to build without abi and for Python3.8 directly
for sublime specifically and also with the abi for the generic python wheel to be
used everywhere else.
reuse as much as possible, keep rpc messages close with their rpc,
helper struct for uuid with into() and from(). also replaced the simple
things, such as imports and struct fields
working on this was really hard, so i'm making simple things first.
removed almost everything except bare buffer changes, and not even done
in a smart way, but should be a working PoC? now trying to make a
working client to test it out and actually work on a real prototype
