Possible bug in outlier clusters

[nomadbl]

Hello, thank you for your work! @dinarior I'm working on adapting the package for easier use, especially inside other software, and possibly some further performance improvements by removing mutables/globals. I've noticed on local_cluster_actions.jl line approximately 50 that the left and left (this is not a typo) clusters are modified as so:

    cpl.suff_statistics.N = sum(group.labels_subcluster .== 1)
    cpl.suff_statistics.N = sum(group.labels_subcluster .== 2)

I think this is a typo bug, but wanted to make sure because I couldn't find a mention of outlier management in the paper which would explain the correct behavior.
