This PR does mainly three things: (1) switch to a "decimating correlator" which outputs 100 kHz wide channels, (2) switches the main packet capture over to IB verbs, and (3) drops back down to two beams. As of today, March 11, 2021, this is the version of ADP actually running (or at least branches based off it) at Sevilleta.
Notes:
For (1) the decimation occurs pre-X and it has helped with some stability problems that we were seeing with the servers related to memory access problems. It has also helped to slightly reduce the power usage at the station without too much of an effect on the science done with the wideband imager.
For (2) this switch has improved the packet capture stability and reduced the "startup lag" that was interfering with the lightning self-triggering mode. However, like PR #4, this relies on a Bifrost branch in https://github.com/jaycedowell/bifrost/ in order to work.
