url64 is the common name for the base64url described in the
RFC4648 §5.
Since the original base64 alphabet contains invalid characters for URLs a safe
base64 for url is suggested, replacing the 62nd (plus sign +) and 63rd
(slash /) with new chars respectively the minus - and underscore _ and
removing also the padding that is represented with the equal sign =.
This a handy small utility to encode/decode strings in url64 with python3 very useful for JWT
