v1.0.0-rc.123 (#30)
This is an UNSTABLE release.

* jfjoch_broker: Use newer version of Google Ceres for (potential) CUDA 13 compatibility
* jfjoch_broker: Improve performance of generating preview images, especially for large detectors (9M-16M)
* jfjoch_viewer: Improve performance of displaying images, especially for large detectors (9M-16M)
* jfjoch_viewer: Add more color schemes for better image readability
* HDF5: Common mutex for reading and writing HDF5 if both operations were to happen in the same executable
* HDF5: suppress warning if path (upstream group) doesn't exists when checking if leaf exists
