Changed UF reference volume update approach from time x rate equation to accumulation of step time x rate. Fixed debug logging of event data when alarm is triggered. Updated flow test build output.
Added misc test/debug build flags. Added persistence to CAN buffer overflow faults so that we can try to recover from one-off spurts when a node is coming online.
Added safety shutdown override command support. Zero treatment duration param in response to UF adjustment message if time adjustment should be disabled.
Added test code that can read slow page of FPGA. Added test code for flow signal strength and occlusion sensor debug output for h/w testing. Delayed reservoir switch until after DG has flushed lines and started recirculating in order to get a more stable reading on load cells.
