v1.0.0-rc.96 (#1)
This is an UNSTABLE release.

* Fixes in CI pipeline
* jfjoch_broker: Remove PNG preview, no dependency on libpng
* jfjoch_writer: Fix UTC timestamp being generated wrong (mix between milli- and microseconds)
* jfjoch_viewer: Show data collection time in dataset tooltip
* jfjoch_viewer: Allow to choose the calibrant (presets for LaB6 and silver behenate)
* jfjoch_viewer: Auto foreground value
* Use external libjpeg-turbo and libtiff: simpler build stack, these are built and linked statically in automated Docker builds
* Remove OpenBLAS dependency
