Feat/session readonly

[wrjgold]

Description:
Adds an option to invite other users to a session as viewers (read-only mode) or editors.

Changes:

• Upon invite request

  • Generates a session uuid
  • Generates 2 additional shorter ids (6 characters) for easier reference, one for viewer’s session and one for editor’s session
  • Saves the ids in a map object and stores in the document set object
  • Returns session uuid and read only status set as false

• Upon join request

  • Matches input id with corresponding session uuid and read-only status
  • Returns session uuid and read only status set as false/true
