Milestone #20350: IOTA BPM deployment
Support multiple sets of coefficients for 2-D fits
Right now the IOTA BPMs use a 2-d fit for their position calculation. The co-efficients are hard-coded, but there is at least one BPM at IOTA that needs to use a different set of coefficients.
There are ~30 coefficients for the fit, so specifying the same coefficients over and over again on the BPM-level in bpmd.conf would be cumbersome. There should be some way of specifying "default" coefficients for all BPMs and then over-riding with a different set of coefficients on the BPM-level.
