prerequisite for #857
With this PR, Rauthy has fully custom JWT creation / singing / verification. This made it possible to completely drop
jwt_simple
as a dependency, which removed 21 other external dependencies overall, and makes it possible to integrate PQC algorithms in the future. This custom impl also made all JWT related operations a lot more memory efficient and faster, with way less memory overhead and allocations.All integration tests are green again and I fixed a few minor other issues while doing the impl. The integration tests use an external crate to check the token validation, and it has been checked with other clients manually already as well.
