v1.0.0-rc.146 (#56)
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.
