Clear() reallocated sum and count but left sum2 as the constructor had
sized it. Every caller reuses one profile across the images of a dataset
(rugnux keeps one per worker, the viewer one per view), so the squares
kept accumulating while the means restarted at zero: the per-image
standard deviation written to /entry/azint and shown in the plots was
meaningless from the second image on, and grew without bound over a run.
The size mismatch was the sharper edge. Clearing to a mapping with a
different bin count left sum2 shorter than sum, and GetStd() and
operator+= then read past its end - reachable in the viewer by opening a
dataset with a wider q range than the one before it.
Both are covered by tests: the same frame twice with a Clear() in
between has to give the same standard deviation, and a profile cleared
to a wider mapping has to report the right value in a bin that only the
wider mapping has.

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
This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132.
* jfjoch_broker: Azimuthal integration mapping is generated with parallel computations, significantly reducing setup times
* frontend: Fix selection of FFTW in indexing settings
