Allow skipped subpanels in fit-grains

psavery · ZackAttack614 · commit 7e6bf3d41d39 · 2026-03-23T13:16:57.000-04:00
This allows subpanels to be skipped in the fitting method. This
happens if there is no HEDM signal on a particular subpanel.

It prevents an error like the following:

```python
File ".../hexrd/hedm/fitting/grains.py", line 251, in objFuncFitGrain
    results = reflections_dict[det_key]
              ~~~~~~~~~~~~~~~~^^^^^^^^^
KeyError: 'eiger_0_0'
```
