v1.0.0-rc.150 (#60)
* jfjoch_broker: When in FPGA workflow (with PSI detectors) azimuthal integration might be forced to CPU - this will require more computational power, but it enables more integration bins and reports standard deviation of each bin.
* jfjoch_broker: Raise error if one is in FPGA flow and there are too many azimuthal integration bins.
