Add secure teach-in

[zuckschwerdt]

The lib is working great and well written, so here is my addition of secure teach-in and secure PTM.

This adds

• RORG constants for the secure modes
• the D2-03-00 VLD EEP
• a SEC_TI pseudo-EEP
• SecureDevice with MAC verification and VAES decryption
• Application translation from SECD to matching VLD D2-03-00 for application type PTM
• Profile translation from VLD D2-03-00 to RPS F6-02-01
• SecureStore for paired devices with teach-in and decryption
• Basic tests for teach-in, verification and decryption
• A commented example to get started

Well tested with PTM215 DB (implicit RLC mode) only, I couldn't acquire the new PTM215 DC :/
The explicit RLC isn't fully implemented, I hope this good enough to get support for secure mode going!

Added pycryptodome to the actions to complete the tests.
I didn't add pycryptodome to the requirements to keep the secure mode optional.

Coverage increased (+0.6%) to 91.959% when pulling 8b6a272 on zuckschwerdt:feat-secure into 12da815 on kipe:master.

Let me know if this PR is interesting to you and if I should enhance the tests to cover the fail cases!
