Still very early stage.

So far this PR includes:

  • updates in the API
    • support for setting different methods and crypto suites (even though only one is supported for now)
    • a separate function for setting identity (private key + credential)
  • a new buffer struct that is parameterizeable via const generics
  • a new credential struct that supports CCS's that hold asymmetric and symmetric keys
  • improved handling of ID_CRED_x, including support for kids longer than 1 byte

Next steps are to update the examples and C/Python wrappers, then merge on main and continue the agility work on a new PR.

@malishav just asked for a review, mostly interested in an ack about the changeset (in comment above).

One point I have is that the Symmetric key type would not need to live in main, but not keeping it in main means having to keep another version of the code just for that, which in my opinion is not worth it.

Also, regarding actual crypto agility, I will leave for another PR since this one is already big enough...
