Review open recon-related PRs in QSIPrep repo

[tsalo]

Summary

We should see if there's anything we want to reproduce in QSIRecon that's currently targetting QSIPrep.

At a glance, the following four seem to be recon-related:

• WIP [ENH] Add singleshell benchmarking recon workflow qsiprep#780
• [DOC] Update reconstruction.rst qsiprep#746
• [DOC] Describe mrtrix connectivity matrix outputs qsiprep#689
• pyAFQ pipeline: Use previous analysis derivatives as inputs for masks: seed and brain. qsiprep#571

2/4 have been closed and I've pinged the others about copying over the changes to QSIRecon. Going to close this issue.
