geosketch v1.2
Updates to new sklearn API from #10
In v0.24 sklearn.cluster.k_means_ was deprecated so it's been changed to sklearn.cluster._kmeans in kmeanspp.py.
Additional minor fixes:
- fixed method name in reduce_dimensionality error message
- removed old scanpy.api interface in favor of just scanpy
- bumped geosketch version to 1.2
