Retag wheels to be cpXY (#644)

Fixes #641

After building the wheels, this...

* Creates the tag string from `cp` (CPython) and the `python`'s version
* Uses the tag string to replace the `python_tag` and `abi_tag`
* Removes the previous wheels while performing this conversion
* Hands them to `auditwheel` for final steps
