feat: fal file

[badayvedat]

Example part in a pyproject.toml

[tool.fal.apps.my-app]
ref = "inference.py::MyApp"
auth = "shared"

this will be converted to something like

fal deploy inference.py::MyApp --app-name my-app --auth shared

We should eventually make this a typed dict or a data class so we have stronger typing and that way caller functions have guarantees about what fields they can expect to access
