Add Immich support

Please add support for Immich.

Idea:

  • MVP: support a write only mode for general import Data to Immich
  • MVP: Support mount to specific Albums (read-only)
    —————
  • More enhanced 1: Mount as read-write: while the upload does an Import and attach the mounted Album to the Photo.
    e.g. add a virtual import directory on the root of the mount
  • More enhanced 2: allow to delete
  • More enhanced 3: allow to steer the virtual directory
    e.g. allow to set-up the virtual directory structure by date, recognized people, flat, oder also-attached Albums
  • More enhanced 4: allow to full edit Picture
    e.g. edit in Gimp, add Tags, etc.
