<doc>
Extracts the assignment information from immediate assignments, i.e. timeslot, channel type, etc.
Input: decoded control channel messages
If "Print" is enabled, the information will be printed to output also,
else the data can be retrieved using functions:
get_frame_numbers(), get_channel_types(), get_timeslots(), get_subchannels(), get_hopping(), get_maios(), get_hsns(), get_arfcns(), get_timing_advances(), get_mobile_allocations()
If "Ignore GPRS" is enabled, the extractor will ignore Immediate Assignments that assign GPRS channels.
If "Unique per request ref" is enabled, the extractor will capture the first Immediate Assignment for every unique request reference, and ignore further duplicate assignments
