Add NxpKeyPrivileges (Register) for the Table 5 AES key-privilege byte
and bind it on the NxpAesAuth mixin (ICODE DNA + NTAG5 Link/Boost):
- read / write / privacy / destroy / eas_afi / crypto_config /
area1_read / area1_write, each a documented bit
- NxpKeyPrivileges.build(read=True, write=True, ...) keyword builder
- tag.key_privileges(key_id) / tag.set_key_privileges(key_id, value)
Additive: the existing PRIV_* constants and has_privilege() path are
unchanged and see the same bytes. 5 new tests.
