added another channel that denotes iDQ data was present

As requested by John Z to ease incorporation within the DMT processes. I took the easy approach, simply defining another channel using the channel name template at the same sample rate as everything else. We may be able to get away with a lower sample rate (essentially just one sample per frame), but that'd take a lot more work to re-route the plubming and support multiple sample rates within our "seriesdict" objects passed to our SeriesReporters.

I tested this with a quick batch job and everything seems happy. I can read and write frames with the standard Reporters just fine.
