Closes #1 Closes #3

Adds a bunch of support for stuff not in the grammar
Fixes a bunch of things in the grammar
Adds tests for much of the above
Adds comment and pragma handling/association with Python dataclasses (more work will be required here)
WIP: temporarily moved out IL stuff; will move it back and support it
WIP: FB Property support

Once all the grammar dataclasses are built out, then it'll be onto making accessing information easier.

I'll work on finishing the summary tooling in another PR. I think this is good enough for the first pass.
