v1.0.0-rc.170 (#80)

* Fixed a `jfjoch_broker` crash during indexing: sorting no longer misbehaves on non-finite values, and GPU FFT indexer kernel launches are now error-checked.
* rugnux needs about a third less peak memory to scale, merge and post-refine rotation data, with identical results.
* `rugnux --model`: the placed coordinate file carries the space group its own coordinates obey, and says so when that is not the group the reflection files beside it carry.
* `jfjoch_viewer`: fixes in the dataset plots, inspector and layout; spot markers lose their black outline by default (a checkbox under "Image features" restores it) and the highest-pixel markers are white boxes around the pixel.
