Sort Datasets in a Virtual Folder Structure

[fm3]

Users should be enabled to sort datasets in a folder structure in the webKnossos UI.

(I suggest we move the checkboxes to the PR description once one exists)

• [ ] Backend
  • [ ] SQL Schema, compare https://www.slideshare.net/billkarwin/models-for-hierarchical-data
  • [ ] CRUD routes for folders
  • [ ] routes to move datasets
  • [ ] permission system
    • [ ] directories get allowedTeams just like datasets
    • [ ] dataset managers + admins can read+write in any folder
    • [ ] users can read
    • [ ] team managers can write in directories where the team they manage is allowed
    • [ ] additive permission bubbling through the folder tree
    • [ ] when you can read a leaf but not the parent, you still get to know the full path (but listdir will only lead you to the particular leaf)
• [ ] Frontend
  • [ ] current directory table view
  • [ ] sidebar with actions + metadata
  • [ ] context menu with actions
  • [ ] left-side tree view
