diskset option requires spaces in between disks

SUMMARY

The diskset option is documented as --diskset name:sda,sdb but in fact in order to work you have to pass as --diskset "name:sda, sdb", note the added space after the comma and the required quotes.

OS / ENVIRONMENT

Running on macOS 13.4.1 (22F82)

STEPS TO REPRODUCE

I attempted to separate out my SDD and the disks forming my ZFS pool with the following command:

dool --cpu --net --disk --disk-tps --bytes --diskset sdd:sda --diskset 'zfs:sdb,sdc,sdd,sde,sdf,sdg,sdh'

EXPECTED RESULTS

I should have seen IO operations for the zfs set.

ACTUAL RESULTS

The zfs set showed no operations whatsoever. Creating a set for each of the disks individually worked. Looking at the code parsing the arguments it is splitting on ", " so I tried adding spaces in between the disks in the disk set and that worked.
