itacac: Disable the passing of SNR time series around triggers in the outgoing

buffer, also disable the subthreshold SNR time series retrieval. This patch is
to decrease runtime of production offline runs, and will need to be reverted if
you want to get the SNR time series for event files. Do *NOT* push to master.
