- BREAKING CHANGE: all method parameters `jwk`, `sig_jwk`, `enc_jwk`, or `jwk_or_password`, accepting a `Jwk` instance
have been renamed to `key` or `sig_key`,`enc_key` or `key_or_password` respectively.
They now accept either a `Jwk` instance, or a dict containing a JWK, or a `cryptography` key instance directly.
- Added `Jwt.sign_arbitrary()` to sign JWT with arbitrary headers, for testing purposes only!
- Updated dev dependencies
