Add types to appease mypy!

[bh2smith]

Mypy complains and I have to silence it like this (which is not ideal).

from multiformats_cid import from_bytes  # type: ignore

If the project is already typed, then it should be as easy as adding an empty file called py.typed to the base module.

and adding this to setup configuration:

[options.package_data]
<YOUR_SRC_DIR> = py.typed

However, I went looking for the code here and I don't see any:

From what I can tell, there is only one file in this project (although it doesn't appear to be here).

If someone could link me to it I can add the types.

Seems like you've found the right place to post this.
