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 Reviewed-on: #58
