WIP: rel/2106.1

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

Accepting this merge request will cause the conda recipe for fsl/eddy to be updated to version 2106.1.

If all goes well, a new conda package will built for fsl/eddy (2106.1), and will be uploaded to the FSL production conda channel.
