- variant for `authorization_mode` in `AuthorizationReq` has been
  introduced
- sdp packet buffer size has been increased to 4k, in order to be large
  enough to contain sample data from josev
- crucial bug has been fixed in `ServiceDetail` serialization, where the
  `ParameterSet` has not been initialized/zero-initialized properly --
  this will need some follow up discussion
- some PnC related message and state handling has been added/refactored
- minor refactorings on conversion functions

This looks good as preparation for the PnC implementation 👍

I would suggest that you change the PR title. With the current title one could think that the complete PnC implementation will take place here and then PnC will work. Which is not the case.

Maybe we should start to use std::array instead of a c buffer.
I am fine with increasing the buffer size to 4096. I think that's more of an experience value. 4096 should be enough for now.

Here we should send also the contract cert chain from the AuthorizationReq message as well. But only once.

This does not have to be part of this PR, but will be added when PnC is fully implemented.

We should move this feedback.signal call to the authorization state. Only in the authorization state is it clear whether the car is requesting PnC or EIM.
