// APDU commands are defined as part of ISO 7816-4. Commands can be serialized
// into either short length encodings, where the maximum data length is 256
// bytes, or an extended length encoding, where the maximum data length is 65536
// bytes. This class implements only the extended length encoding. Serialized
// commands consist of a CLA byte, denoting the class of instruction, an INS
// byte, denoting the instruction code, P1 and P2, each one byte denoting
// instruction parameters, a length field (Lc), a data field of length Lc, and
// a maximum expected response length (Le).
