It's a major reorganization.

Browse Source 
In order to add FIDO2 support, we need to reorganize some USB/CCID calls to specific area (named driver).
Thus, pico-hsm-sdk has two drivers:
- CCID driver implements APDU over USB/CCID ISO-7816 standard procedures.
- HID driver implements APDU over HID.
