(Script request) Add a script to mount the RedoxFS partition of the dual-boot Redox installation

The purpose of this script is to automatically mount the RedoxFS partition of Redox installations on the same storage device, be it from the dual-boot.sh script or the installer.

The script will do the following things:

• Verify if libfuse 3.x is installed, if not give an error message warning to install it
• Run the setfacl tool to allow the redoxfs execution to be rootless (sudo setfacl -m u:current-user:rw /path/to/disk)
• Verify if a RedoxFS partition exists on the storage device, if yes get the location
• Give the partition location to the redoxfs executable and mount

Also add an option to umount the partition.
