lib: base64: add support for base64url
base64url has some small differences to our current base64 implementation:
- Instead of encoding to `+', `-' is used
- Instead of encoding to `/', `_' is used
- Padding with = to reach four byte boundary is optional
- Invalid characters aren't silently skipped
Everything else is the same though, so let's reuse the code and have an
optional url bool parameter control whether to decode base64 or
base64url.
