base64encode applies Base64 encoding to a string.
Nomad uses the "standard" Base64 alphabet as defined in RFC 4648 section 4.
Strings in the Nomad language are sequences of unicode characters rather than bytes, so this function will first encode the characters from the string as UTF-8, and then apply Base64 encoding to the result.
The Nomad language applies Unicode normalization to all strings, and so
passing a string through
base64decode and then
base64encode may not yield
the original result exactly.

base64decodeperforms the opposite operation, decoding Base64 data and interpreting it as a UTF-8 string.
