Create cubids mv command to rename individual files or directories

[tsalo]

Closes #452. Currently just the outline of an idea.

Changes proposed in this pull request

• Create a new CLI, cubids mv, to rename individual files or full directories. I'm modeling it on git mv.

Here's my plan for the behavior:

Move a file

cubids mv infile outfile

This renames the file and associated files, like a regular rename in cubids apply.

Rename a subject

cubids mv sub-01 sub-02

This renames the folder and the files in that folder. Each file being renamed basically goes through the same process as a separate file rename. Plus, since this is a whole subject, the participants.tsv should get updated too, along with any other top-level files that contain subject IDs.

It should update the following files:

• participants.tsv
• sub-01/sub-01_scans.tsv
• sub-01/ses-/sub-01_ses-_scans.tsv
• sub-01/sub-01_sessions.tsv

Rename a session

cubids mv sub-01/ses-1 sub-01/ses-2

This renames the folder and the files in that folder. It should update the following files (assuming they exist):

• sub-01/sub-01_sessions.tsv
• sessions.tsv (coming in a new BEP)
• sub-01/ses-1/sub-01_ses-1_scans.tsv
