Ended up writing my own CST and added it to that library of mine (link above).
My target is adding/removing/changing of: docstrings, function return types,
function arguments, and Assign/AnnAssign. All but the last are now implemented.
I was careful not to replace code elsewhere in my codebase, so everything
except my new CST code (in its own files) stays, and everything else works
exclusively with the builtin `ast` module as before.
