0.23.0

• Fixed MyPy errors (courtesy @sinisaos).
• Simplification of JWT authentication - it no longer needlessly checks expiry, as PyJWT already does this (courtesy @aminalaee).
• Substantial increase in code coverage (courtesy @aminalaee and @sinisaos).
• Increased the minimum PyJWT version, as versions > 2.0.0 return the JWT as a string instead of bytes.
• Added an option to exclude columns when using create_pydantic_model (courtesy @kucera-lukas).
