WIP: rel/1.1.1

This merge request was triggered by a new tag being added to the fsl/fsl_mrs project.

Accepting this merge request will cause the conda recipe for fsl/fsl_mrs to be updated to version 1.1.1.

If all goes well, a new conda package will built for fsl/fsl_mrs (1.1.1), and will be uploaded to the FSL production conda channel.
