v1.0.0-rc.178 (#88)

* Rugnux: Processes serial crystallography data from XFELs - SACLA (MPCCD), PAL-XFEL and European XFEL (CXI), LCLS (XTC) and SwissFEL Alvra (JUNGFRAU with a CrystFEL module geometry) - with several files or Jungfraujoch master files merged in one run (`rugnux *_master.h5`).
* Rugnux: Stills processing takes a known unit cell and space group as a starting point, finds the beam centre (and, with a cell, the detector distance) from the images, detects the saturation level in other facilities' files and refines the placement of individual detector panels.
* Rugnux: The stills report gives R_split and CC1/2 from frame half-sets, comparable with CrystFEL.
* jfjoch_viewer: Opens the same XFEL file formats.
* Validation: A stills battery checks Rugnux against deposited structures from SACLA, PAL-XFEL, LCLS, European XFEL and SwissFEL.
* Rugnux: More reliable convergence of rotation scaling, and live molecular replacement starts as soon as the model is uploaded.
* jfjoch_broker: Initialize clears the previous dataset's bearer tokens, image buffer and live Rugnux status, and a slow CUDA JIT cache is reported at start.
