Feature Request: members-in-groups

[wmodes]

Currently, the num-group parameter allows you to specify how many groups. This is often less useful than being able to specify how many members are optimally in each group.

This also begs the question of how to handle uneven distribution: Would it be better to create a few smaller groups, or to create a few larger groups? This can be handled with a boolean, i.e., --bigger-groups true or more precisely with min and max, i.e., --min-group 4 or --max-group 4
