This updates the logic of parsing bytesize into size/unit pair.
Currently 'GiB' is set as a default which causes problem with smaller partitions on Edit.
A validation for the min_size is in place and the rule is that the size cannot be smaller than 0 of a given unit. If there was a partition with smaller size in KiB it will break the rule when converted to GiB.
