Hotfix release for metadata change at SST1

Urgent release to fix 49 which is blocking testing EliotGann is doing at SST-1 (pbeaucage)

**Full Changelog**: https://github.com/usnistgov/PyHyperScattering/compare/0.1.7...0.1.8

- Fixes for incompatibilities in xarray (pbeaucage)
- support for polygon masks in integrators (EliotGann, 37 47) and better integrator testing
- revamped CyRSoXS support (pdudenas 41 and others)
- fixes for metadata format changes in SST-1 RSoXS suitcased data (pdudenas 40)
- updates to SST1 databroker loader including multi-scan loading (pbeaucage)


**Full Changelog**: https://github.com/usnistgov/PyHyperScattering/compare/0.1.6...0.1.7

- Integration consistency/bugfixes from ktoth17 (35, 34 , 36)
- Fault tolerance in SST1 RSoXS monitor loading pbeaucage

Many updates, largely to SST-1 instrument support and integration

- tabulated geometry values include updates for newer runs, thanks cbishop4
- Nika-space integrator parameters can be tweaked on-the-fly as attributes
- Monitors are now supported for SST-1 data broker loading. (lots of work by EliotGann and pbeaucage)
- SST-1 data broker now has a flexible search engine.

Add integrator dynamic geometry translation/tweaking.

Hotfixes for SST-1 data loading.
**Preliminary, untested, pre-production API, ** support for sine/cosine fitting of anisotropy ratio (thanks dsunday)
