PixelRefine's reference can now be a merged/observed-intensity MTZ, not only a
calculated F-model. If F-model is missing, read a mean-intensity column (IMEAN,
which a jfjoch merge writes; also I/IOBS/Iobs/I-obs, or any 'J'-type column) and
use it directly as I_ref (F-model is squared, intensities are not).

This enables a SELF-SEEDED / EM-style workflow: run a first pass (traditional
integration, or PixelRefine against an external reference) to produce a merge,
then re-run PixelRefine with `-z <that merge>.mtz` so it scales against the data's
own intensities - free of the reference structure's non-isomorphism bias - and
iterate. Verified: a jfjoch IMEAN merge loads as the reference and PixelRefine
runs against it (crystal 2, 55279 reflections, CC1/2 94.3).

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_process: Generate a dedicated file (_process.h5), which can be used as a replacement for the _master.h5 file for a reanalyzed dataset.
jfjoch_process: Improve the performance of scaling and merging, implement on the fly scaling.
jfjoch_writer: All final data analysis results are repopulated in the _master.h5 file.
jfjoch_scale: Dedicated tool for rescaling/merging existing data.
jfjoch_viewer: Fix bugs where pixel labels where displayed on a wrong pixel.

WARNING! Scaling and merging are experimental at the moment, and may not provide reasonable results for the time being.
