Jon Dufresne 6a6561c2cb Move many type comments to annotations
Use the tool com2ann to automatically convert most type comments to type
annotations. Some type comments continue to exist where any work beyond
the automatic conversion was required (for example, additional
formatting or circular references).

For additional information on the com2ann tool, see:

"""A helper module that injects SecureTransport, on import.
The import should be done as early as possible, to ensure all requests and
sessions (or whatever) are created after injecting SecureTransport.
Note that we only do the injection on macOS, when the linked OpenSSL is too
old to handle TLSv1.2.
