* Fix small error in venv setup guide
* Add functions for mm integration
Implemented: create channels for groups
Implemented: create webhooks on both sides for groups
As for now these functions can only be called from the Python REPL
* Add commands for mm channel/webhook creation
Implemented: archive a given list of channels (unused)
* Add new features to README
* Add filter argument for channel/webhook creation
This filter argument is optional and defaults to an empty string,
meaning no filtering is required. This is helpful for excluding previous
project repos or irrelevant repos.
Also added detection logic to handle an exception where a student is on
MM but not in the target team. (Perhaps we would want to invite that
student immediately?)
* Update README
Clarify platform difference for venv
Restructure Commands & Features section to make room for better docs
* Remove unused function from Canvas worker
* Add gitea domain name and suffix config items
Align with the mm worker, and grant more flexibility
Also changed terminology to be clearer (`domain_name` instead of `url`)
* Code style and quality updates
* Add domain name and suffix config items for Canvas
* Return to using dicts to represent groups
Removed `StudentGroup` at BoYanZh's request
