I agree with it too. It is neater to add "base64url" as a new option for
encode() and decode() SQL functions in encode.c.

In addition, you may also want to add the C versions of base64rul encode
and decode functions to "src/common/base64.c" as new API calls so that
the frontend, backend applications and extensions can also have access
to these base64url conversions.
