First steps and planning

@hoodmane @rth @ryanking13

These are the first steps where I could focus my energies for now:

• Copy the source code of the generator in this repo (the linked repository contains more than that, so I will not bring in the history of everything there. Just that folder in the current state.
• Organize the project with the src layout.
• Run the tests of the generator on every push through GitHub Actions
• Write some documentation
• Create some script/automation to generate the js.pyi artifact and push it to pypi
• Bring in the existing open issues from the other repo
• Plan something to join manual webidls (sadly I noticed that no one webidl source is enough...) now the best webidl source I know is from w3c/webref/curated

And then these points are for adding comments to the api:

• Investigate how to gather the information about api platform availability (probably from the webidl files)
• Gather/harvest comments from MDN (maybe there is some structured information about the previous point?)

What do you think?

Start by reviewing the js_pyi generator source and the proposed src layout. Then inspect how its tests can run through GitHub Actions on every push, and how the generated js.pyi artifact could be published to PyPI. The issue lists documentation, imported issues, WebIDL sources, and MDN comments as additional planning areas, so completion is not narrowly defined.
