Notes
A User Identity (RQ) Sub-item requires the following parameters:
Item type (1, fixed, 0x59)
Item length (1)
Server response length (1)
Server response (1)
Encoding
When encoded, a User Identity (AC) Sub-item has the following structure, taken from Tables D.3-15 1 (offsets shown with Python indexing). Items are always encoded using Big Endian 2.
