[capture] Simple script for KMAC

[nasahlpa]

As the old capture.py file is not working anymore due to the repo restructure, we need to implement the KMAC capture.
Please use capture_aes.py as a boilerplate.

I'm working on this. However, it will take some time to test it in the office.

Technically KMAC (and SHA3) doesn't have a ciphertext, but a tag. In the past, we used the term ciphertext (and the associated fields) to refer to the Tag/Hash. Should we keep this naming?

[nasahlpa]

I guess it would make sense to use the correct naming, .e.g, tag. I think this increases the readability of the code.

However, the new trace library currently only supports the ciphertext/plaintext/key field. It should be fairly easy to add new fields.

There's a first draft (not PR yet) at 8d40089
The PR is merged. However, there there are two remaining issues:

• still the old variable names
• An AES instance is/was used to generate the next key/plaintext in non batch fvsr mode. However in batch mode the internal prng was used. I think this should be aligned in either case

[m-temp]

I've changed the priority, as the main task is done now. The new kmac capture script has now the same functionality as the old one. However I leave this issue open, as there are still some points to be discussed. See above.

Feel free to close this issue and track the remaining tasks in a different issue
