DetectorSetup gave a DECTRIS detector bit_depth_image = 16 and bit_depth_readout = 16
the moment it was constructed. Both mean "the detector told us", and at construction
nothing has asked it: the SIMPLON client learns them at configure time, and the lite
receiver reads them off the start message. Until then they were an assumption wearing
the clothes of a measurement.
The assumption was load-bearing in the wrong direction. GetByteDepthImage() gives the
detector's image depth absolute priority - correctly, since the DECTRIS path forwards
images verbatim and the depth has to be the one the pixels actually have - so a value
that was always set meant everything below it was unreachable on DECTRIS:
* image_format_settings.bit_depth_image, which the API documents as "bit depth of
resulting image ... if not provided value is adjusted automatically", was silently
discarded. It works on JUNGFRAU, where the detector's value is not set, and did
nothing at all on an EIGER. No error, no warning.
* so was the promotion to four bytes that summation needs.
Both are now unset for DECTRIS. JUNGFRAU keeps its readout depth of 16, because there
that is a property of the hardware rather than something configured.
Where nothing supplies a depth the answer does not change: GetByteDepthImage() falls
through to the same two bytes it produced before, and the fallback no longer throws
merely because the readout depth is not known yet - GetBitDepthReadoutIfKnown() reports
it as unknown instead of inventing one. The start message carries it as an optional
already, and the receiver already guards on that, so "not known" travels end to end
rather than being papered over. GetBitDepthReadout() still throws for the callers that
genuinely require a value; all of them are on the FPGA path, where it is always set.
Also fixes the jfjoch_test build, which the previous commit broke: SpotExtractorGPU's
Extract() takes a PixelView now, and the parity test still passed a raw pointer. That
should have been caught before it was pushed.
Tests: DetectorSetup (with a new case pinning the contract this restores), plus
DiffractionExperiment, CBOR, writer, HDF5, preprocessing, azimuthal integration and the
GPU spot-finding / integration / decoder suites. rugnux unchanged end to end.

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 and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132.

* jfjoch_broker: Further reduce startup time for DECTRIS detectors by not setting beam center and detector distance via SIMPLON API on '/start'
* jfjoch_broker: Add an extra message to ZeroMQ puller ready to monitor Lite worklow preparation time
* jfjoch_broker: Image buffer configuration is postponed for Lite receiver flow till start message is received
* jfjoch_broker: Use nanoseconds internally for frame/image/readout time

**Breaking changes**: detector definition is now using nanoseconds to define minimum frame time, minimum count time and readout time.
