Implement Versioning Similar to faradayio-cli

`faradayio-cli` uses a single location to store the version. This might be useful in `faradayio` as well. However, make sure it's actually useful since `faradayio` is not a command line interface program.

Example use:
* https://github.com/FaradayRF/faradayio-cli/blob/develop/setup.py
* https://github.com/FaradayRF/faradayio-cli/blob/develop/faradayio_cli/faradayio_cli.py
