------------------
* ImagePartition is now responsible for mounting and obtaining its stats, and detecting lvm volumes
* LVM partitions are now mounted using this new mount method
* Utilize the partition size for disk size, which is more reliable
* Renamed ImagePartition to Volume (no backwards compatibility is provided)
* Add unknown mount type, for use with :option:`--fstype`, which mounts without knowing anything
* Support mounting a directory containing \*.001/\*.E01 files
