Improve performance of :func:`base64.b16decode` by a factor ten by
removing an unnecessary regular expression. Consequently, :mod:`re`
is no more implicitly available as ``base64.re`` and import time of
:mod:`base64` is improved by a factor six. Patch by Bénédikt Tran.
Improve the performance of :func:`base64.b16decode` by up to ten times
by more efficiently checking the byte-string for hexadecimal digits.
Reduce the import time of :mod:`base64` by up to six times,
by no longer importing :mod:`re`.
Patch by Bénédikt Tran, Chris Markiewicz, and Adam Turner.
