v0.0.0.9004

New features

• For supervised UMAP with numeric y, you may pass nearest neighbor data
  directly, in the same format as that supported by X-related nearest neighbor
  data. This may be useful if you don't want to use Euclidean distances for
  the y data, or if you have missing data (and have a way to assign nearest neighbors
  for those cases, obviously). See the Nearest Neighbor Data Format section for details.
