qcacmn: Support timestamp verification per-detector

Modify prev_tstamp variable in target_if_spectral
structure to an array and index it based on detector ID.
Also, modify target_if_spectral_verify_ts() to include
detector_id parameter and compare current timestamp with previously
received sample on per-detector level, to check discrepancy.
