Implement notification subcommands (#389)

- [x] enhance notification listing
  - add `--states` and `--type` filters
  - toggle per-user or per-repo listing via `--mine` flag
  - print more fields
- [x] add subcommands to mark notifications as read, unread, pinned, unpinned. operates on
  - all notifications matching the `--state` and `--mine` filter flags, or
  - a notification specified by ID.
- [ ] ~~add a `--fields` flag for notifications listing.~~ *not in this PR*
- [ ] ~~interactive mode~~ *not in this PR*. this would go well together with #324

fixes #243, fixes #155

based on initial work in #283 and #386, but opening a new PR for @6543 to review as I changed quite a lot

---

### ⚠️ breaking ⚠️
- `tea notifications --all` has moved to `tea notifications --mine`
- `tea notifications` now only works with the context of a remote repo.
  To run this outside of a local git dir, run either `tea n --mine` or `tea n --repo <my/repo>`
