Add save session option

### Problem

Files is on of the most important apps in my workflow because every opened tab is a "project" I'm either working on or should be working on (both personal and work related). I often would like to have separate sets of tabs remembered

### Proposal

It would be great if we could save sessions (i.e.: opened tabs) to restore later as a way to organize these "projects"
