Support for payloads with an empty string

[abhishekbhat004]

Can payloads with empty string be handled?
The latest ACME specification requires support for payloads with an empty string ("").
(https://datatracker.ietf.org/doc/html/rfc8555#section-6.3)

Right now if I try to parse a payload with an empty string, I get an exception
com.auth0.jwt.exceptions.JWTDecodeException: The string '' doesn't have a valid JSON format.

Hi @abhishekbhat004, can you provide a sample JWT?
