No pyi files from pip package

[wwwillchen]

I'm working on a project: https://github.com/google/mesop that uses absl and pyright for Python type-checking. Pyright looks for pyi files to resolve type definition.

For example, the logging __init__.py file does not include type hints, however the pyi does include type hints. I use absl via pip install, however the absl pip package does not include any pyi files. When I inspect the source distribution files from absl's pip page, I do not see any pyi files.

If absl includes pyi files, then it'll make it easier for project consumers to do type-checking.
