PEP 561 compatibility: py.typed marker?

[imuli]

Importing edg in my editor with the pylsp-mypy language server, I get a warning that there is no py.typed marker (or stubs).

I'm not terribly familiar with python, but it sure looks like you all are using type annotations. If I'm reading this right all that'd be needed is adding an empty py.typed file to the packages (and maybe something to indicate that it should be added to the packaged module?).
