fzfs umount: umounting now also works for datasets and/or mountpoints that have spaces in their values. For this to work textproc/jq must be installed as /usr/local/bin/jq. "mount -p" is requested as JSON (via libxo) processed accordingly. This is because normally "mount -p" has a TAB as field separator -- with the exception of fields becoming to large; the a SPACE is used... "fzfs mount" works already in this cases.
