Initial release and PyPI packaging

I gather that fossdriver is seeing at least some usage out in the community! It would be great to be able to put together an initial release (even if that's still something like a 0.1.0 release).

I'd say a minimal piece of this will be to make it possible to install fossdriver via pip / PyPI. Rather than having to manually retrieve and unpack the code.

If others have input / experience or can help with moving to an initial point release, or with instrumenting fossdriver to work with PyPI, all help is welcome!
