- Not all kinds of units are comparable. Introduce a method
in PartitionSize to check for comparability (this could
also be a free method, but seems more tidy here because it
is specifically about comparing in the context of partition sizes).
Using PartUtils::PartSize as reference, this commit creates a new
PartitionSize class in libcalamares, which will then be used in every
module needing such a class.
