Adding Extended Cipher feature.

Browse Source 
With this new subcommand, Pico HSM will support newer cipher algorithms.
ChaCha20-Poly1305 is the first. It will be based on a custom P2 subcommand to support an arbitrary structure with multiple parameters (AAD, IV, etc.)

pico-hsm-tool.py shall be used.
