add metrics to segmentation comparison

[berl]

Add ARI score for comparing cell label results, including across hierarchy of labels

[berl]

also mutually-exclusive marker detection

[berl]

if topics extend beyond seg_compare , add a new issue!

luke zhang expressed interest in this, with some potential extension to datasets with different underlying data

[lukezhang-811]

I generated the ARI using mutually matched annotations and looked at how those annotations differ:

Another metric included is Hausdorff which can examine all segmented cells between the two methods. Hausdorff is normalized to the range of the data. In the first example, we have a full tissue comparison.

In the second example, I cut off a section of the tissue and see that the Hausdorff distance increases significantly.

Functions are part of the utils script called returnARI and get_normalized_Hausdorff respectively.
