This PR updates the mrtrix3 interface in nipype and closes issue #3612

List of proposed changes:

1. Added "MaskFilter" for dilate/erode filteres
2. Added "MTnormalise"
3. Added "Generate5tt2gmwmi"

What's the status on this PR? I just found as well that mtnormalise doesn't have interface in nipype.

Apologies for the delay. Please review the change I made (apart from the merge fixing up Zenodo author ordering) and the CI complaints.

Once the tests are passing and you're okay with this, we can merge.

Thank you for reviewing! The changes you made are all good in my opinion.

Unfortunately, I'm rather new to and not familiar with the CI complaints. I won't be able to fix them. I would appreciate it very much if someone could help me out here.
