Milestone #23736: IOTA ACNET Interface Change Requests Dec 2019
Change the data returned in the  element of the BPM TBT array device
Currently the  element of the BPM array device returns 1 and [1:8000] returns TBT data. I believe it was originally intended that this element be an average position, but that is no longer required. Nathan and Chip would like to use this element to return some meta data about the reading.
They are asking for the following:
Bits 0..15 - 16 bit counter than increments (and then rolls-over) on each measurement
Bits 16..17 - 2 bit trigger type: 00 - inj, 01 - orbit, 10 - v kick, 11 - h kick
Bit 18 - 1 bit saturation flag (to be implemented in firmware)
