Test for shortest distance between members in a list and coordinate
Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi
* gn3/computations/slink.py: add code to pass new test
* tests/unit/computations/test_slink.py: new test
Given a list of members in a group, and a coordinate for a member in the
same group, find the distance of the closest member from the given
coordinate in the group.
