Perform the PRACH captures. For each RCID configured in the rach_config, the function will run a demodulation and decimation operation. The data into the demodulation and decimation operation will be extracted from the band and CC specified for each RCID. Demodulation frequency is specified on a per RCID basis. The decimation rate is also specified on a per RCID basis. RCIDs can be restarted by setting the rach_channel_init_flag in the rach_config.
