v1.0.0-rc.181 (#92)
* Rugnux: Several rotation sweeps of one crystal are merged as one dataset (`rugnux a_master.h5 b_master.h5`), on a common indexing and cell, with a non-isomorphous sweep left out and reported; `--sweeps separate` processes each sweep on its own. Bruker `.sfrm` frames and imgCIF files with a full goniometer axis chain are read.
* Rugnux: More robust rotation processing - a retry with a more sensitive spot finder when no lattice is found, a self-consistent detector distance, long axes and doubled cells tested as hypotheses, a `-C` supercell multiple stepped down, and each ice ring merged, down-weighted or rejected on its own.
* Rugnux: Serial stills are merged with a partiality-aware error model, reported as `ERROR_MODEL_A/B/C` with no ISa or R_merge/R_meas/R_pim; runs without `-S` have an overall intensity scale about 0.86-0.88 times that of earlier versions, with unchanged statistics. A second crystal form is left out of the merge and reported, the indexing ambiguity is resolved more reliably, and `--model` no longer influences processing.
* Rugnux: The reported CC1/2 is the standard unweighted one, which can be lower than before on sweeps with weak frames; ISa comes with a 95% interval (`ISA_LOW`/`ISA_HIGH`).
* Rugnux: Model refinement adds anisotropic/TLS, local NCS and twin refinement where R-free supports them; building waters and relabelling ions is now off by default (`--refine-solvent` turns it on).
* NXmx: A detector of several modules is written as `module_0` ... `module_N` only, so DIALS reads each module as its own panel.
* Other: JPEG previews use a bundled encoder (libjpeg-turbo no longer needed), Rugnux prints how to cite it, and the release archives contain the HTML documentation.

<h2 class="jfj-card__title">Rugnux</h2>
<p class="jfj-card__text">Processes a stored macromolecular diffraction dataset, a rotation
sweep or serial stills, from the images to merged data: spot finding, indexing, integration,
scaling and merging, with the space group, cell and resolution decided from the data and a
report that says on what evidence. Given an atomic model it goes on to a refined structure and
maps: the model is placed (rigid body or molecular replacement) and refined against the merge.

:doc:`CERN Open Hardware Licence v2, strongly reciprocal <FPGA_LICENSE>`. Both let anyone, in
academia or industry, use, study and modify the software and the hardware design at no charge,
commercial use included; what they ask is that a modified version which is passed on is shared

Everything a user of Rugnux or the viewer needs comes first; the :doc:`technical reference <TECHNICAL>`
holds the algorithms, the file formats and streams, the interfaces and the FPGA design. The names
are explained in :doc:`Naming <NAMING>`, the releases in the :doc:`changelog <CHANGELOG>`, and how to
