Getting the volume sizes as byte values instead of converted to human readable units helps to avoid rounding errors in the further processing if the volume size is more on the odd side. The `zfs list` command supports the -p(arseable) flag since a few years now. When returning the size in bytes there is no calculation performed and thus we need to explicitly cast the size to an integer before returning it.
