Fix Crema and instrument definition to support ESA Rosetta mission
For [Rosetta](https://repos.cosmos.esa.int/socci/projects/SPICE_KERNELS/repos/rosetta/browse/kernels/mk) the mission metakernel filenames are in uppercase and not found by the tool:
```python
>>> EsaCremasCollection('Rosetta')
<RosettaCremaCollection> Latest version: v340_20220107_001 | No metakernel is available.
```
where these `mk` are actually available:
```
<RosettaCremaCollection> Latest version: v340_20220107_001 | 2 metakernels are available:
- ROS_OPS_V340_20220107_001.TM
- ROS_OPS.TM
```
