NswCommonDecode: trigger decoder test app will now skip non-nsw fragments and keep decoding properly(not affecting online/offline)
the NswCommonDecode has a few code in src/test with main functions that is designed to be ran standalone.
They are supposed to run on raw data from ATLAS but it will attempt to decode non-NSW ROBFragment, causing an error.
This MR will make it skips over non-NSW fragments and does the decoding properly, without the need to pre-filter non-NSW fragment using some other code.
This does not affect online or offline decoding so shouldn't break frozen tier0.
