Implements a sim auth driver that communicates with ofono to handle
GSM/UMTS authentication algorithms. This plugin takes care of
disovering ofono, the modem, IMSI, and SIM capabilities i.e. what
algorithms are supported.
Provides a driver for hardcoding EAP-SIM/AKA keys. The driver
expects the environment variable IWD_SIM_KEYS to point to a
valid config file with IMSI, Kc, SRES for SIM or IMSI, KI, OPC,
AMF for AKA. To use this driver '--plugin=sim_hardcoded' must
be supplied when IWD starts.
