Cstruct woz_aliro_auth0_command

Parsed NFC AUTH0 command: authentication policy and protocol version from the reader, reader ephemeral public key, transaction ID, reader ID, and optional vendor extension.

Cstruct woz_aliro_auth0_response

Parsed NFC AUTH0 response: credential ephemeral public key (65 bytes), cryptogram (variable length), and optional vendor extension.

Cstruct woz_aliro_auth1_response

Parsed NFC AUTH1 response: credential public key (65 bytes), signature (variable length), signaling bitmap, and two signed timestamps (credential and revocation, each 20 bytes if present).
