New CompressionAlgorithm that emits a standard Zstandard frame: zero/0xFF runs
become RLE_Blocks (like BSHUF_ZSTD_RLE) and literal regions become
Compressed_Blocks with per-block adaptive Huffman literals and no sequences
(Number_of_Sequences=0). Short runs are absorbed into the literal stream;
incompressible literals fall back to Raw_Blocks so the worst case stays within
ZSTD_compressBound.
The Huffman tree + bitstream are produced by zstd's own HUF_compress{1,4}X_repeat
(the same calls ZSTD_compressLiterals uses); only the frame/block/literals-section
framing is hand-written, with comments citing zstd_compression_format.md so it can
be checked clause by clause. Output decodes with stock ZSTD_decompress, so no
reader changes are needed (decode routes like BSHUF_ZSTD).
On sparse diffraction this gives ~12% smaller files than bitshuffle/LZ4 at about
the same end-to-end speed, sitting between LZ4 and full ZSTD; for maximum ratio
use BSHUF_ZSTD. Robust on any input: tests round-trip pure zeros, Poisson(10),
Mersenne-Twister noise (checked against the size bound), an extreme-sparsity mask,
and a real lyso image through stock ZSTD_decompress.
API: exposed as "bszstd_rlehuf"; regenerate the Python/TS clients (update_version.sh)
to surface the new value there.

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

This is an UNSTABLE release. The release has significant modifications for HDF5 writing logic - in case of troubles go back to 1.0.0-rc.144.
* **Default HDF5 writing mode is with VDS, not soft-links** - this improves DIALS compatibility and makes format more future-proof, NXmx legacy format might be phased-out in the future.
* XDS plugin: Improve performance of VDS reading.
* jfjoch_writer: Significant improvement on how file systems I/O are handled through a dedicated pass-through VFD.
* jfjoch_writer: Clean-up of HDF5 routines to better handle issues.

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.
* Multiple small bug fixes scattered across the whole code base. (detected with GPT-5.4)
* jfjoch_viewer: Improve image render performance
