Handle timeouts and rate limiting errors more gracefully

[eyeseast]

Right now, the whole stack trace is being printed, which breaks the progress bar, and it doesn't actually stop geocoding.

Here's an example:

Well, maybe there's an easier solution here: Installing requests causes GeoPy to use the RequestsAdapter instead of urllib, and all the errors above go away.

It's optional for GeoPy, but adapters are sort of buried in the docs and it immediately makes things work better. That makes me think I should just add requests as a dependency here and encode a best practice.

Probably also worth increasing the default timeout from one second to five (or maybe higher). One of my goals with this whole library is to be able to run this in the background and trust that it'll finish eventually, or pickup where I left off if needed.
