[IDEA] allow sshfs mount remote storage (rights access issue solved for sshfs)

[Phil35]

ok
I made a test
first: backup of /mnt/SDCARD
with command:
cd /home/pi
tar -C /mnt -cvf moodeaudio.SDCARD.tar  ./SDCARD
./SDCARD/
./SDCARD/Stereo Test/
./SDCARD/Stereo Test/LRMonoPhase4.flac

then sshfs mount:
sshfs -p 54321 -o reconnect,ServerAliveInterval=15,ServerAliveCountMax=3 philippe@192.168.6.237:/music /mnt/SDCARD
philippe@192.168.6.237's password:

cd /mnt/SDCARD
df -H .
Filesystem                     Size  Used Avail Use% Mounted on
philippe@192.168.6.237:/music  3.0T  2.1T  898G  70% /mnt/SDCARD

I also tried to mount in "/mnt/SDCARD/Stereo Test"
It seems working as I read in the log:
20230118 162744 thumb-gen: Scanning: NAS, SDCARD

20230118 162757 worker: Job update_library done

However nothing on the screen .. click on "SDCARD" shows nothing.
