WIP: Bring nirodents brain extraction to anatomical preprocessing

[mgxd]

This PR adds a patch module to include patched workflows and functions from upstream dependencies (smriprep, niworkflows, etc).

One thing to note: there are a lot of connection fields with "*t1w*" in the name. I've changed them within the top level workflow, but doing so in the subworkflows will require essentially patching all of smriprep.

I think you need to change this to fmriprep_rodents:

not smoking 😄 , merging this in and then fine tuning as necessary.
