v1.0.0-rc.153 (#63)
This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use.

* jfjoch_broker: Add EXPERIMENTAL pixelrefine mode for image processing
* jfjoch_broker: Allow to load user mask from 8-bit and 16-bit TIFF files
* jfjoch_broker: Add ROI calculation in non-FPGA workflow
* jfjoch_broker: Fixes to TCP image pusher
* jfjoch_broker: Remove NUMA bindings
* jfjoch_broker: Improvements to indexing
* jfjoch_broker: For PSI EIGER, trimming energies are taken from the detector configuration (now compulsory) instead of hardcoded values
* jfjoch_writer: Save ROI definitions and the per-pixel ROI bitmap in the master file; azimuthal ROIs support phi (angular) sectors
* jfjoch_viewer: Major redesign with dockable panels and saved layouts, plus on-canvas creation/move/resize of box, circle and azimuthal ROIs
* jfjoch_viewer: Run jfjoch_process reprocessing jobs from inside the GUI and overlay per-run results
