/**
* {@code TokenResolver} defines methods for creating, extracting, and
* renewing tokens, particularly JSON Web Tokens (JWTs). It provides a set of
* methods to generate tokens with various payload configurations, extract
* payload from tokens, and renew expired tokens.
*
* Token Creation:
* The interface provides overloaded methods for creating tokens with different
* payload configurations, including expiration time, audience, subject, and
* custom payload data. Clients can choose the appropriate method based on
* their specific token requirements.
*
* Token Extraction:
* The interface includes methods to extract payload information from a given
* token. Clients can use these methods to obtain the payload data encoded in
* the token.
*
* Token Renewal:
* The interface also offers methods for token renewal. Clients can renew an
* expired token by providing a new expiration time, audience, subject, and
* optional custom payload data.
*
* @param the type of the result obtained by the
* third-party library when parsing JWTs
