WIP: rel/v1.2.1

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

Accepting this merge request will cause the conda recipe for fsl/eddy_qc to be updated to version v1.2.1.

If all goes well, a new conda package will built for fsl/eddy_qc (v1.2.1), and will be uploaded to the FSL conda channel.
