v1.0.0-rc.148 (#58)
This is an UNSTABLE release. The release has significant modifications for data processing - in case of troubles go back to 1.0.0-rc.144.

* jfjoch_broker: Improve azimuthal integration (add <I^2> calculation)
* jfjoch_broker: Fixes around indexing, aiming to handle multi-lattice crystals (work in progress, it is not fully integrated)
* jfjoch_writer: Save mean(I), stddev(I), and count(I) for each azimuthal bin
