Is your feature request related to a problem? Please describe.

I would like it if, when re-opening Neovim and NeoTree in a project directory, NeoTree could restore the state of expanded/collapsed folders in the file tree from the previous session, to avoid having to re-expand certain folders again after every restart.

Describe the solution you'd like.

Having a config option to enable NeoTree to store the state of expanded/collapsed folders in persistent storage and, when NeoTree is first opened in the next session, restore that state.

Describe alternatives you've considered.

would you like this to just be done irrespective of whether you're using Vim sessions? like say, neo-tree just keeps a file around that tracks the latest set of opened nodes for a given root dir and when you open a new instance of neo-tree in that root dir, it'll read that file and open the nodes back up automatically?
