Inverse Transform?

Hi!
Cool project! If there any plan to implement an inverse op: embedding -> data ? Something like

http://scikit-learn.org/stable/modules/generated/sklearn.decomposition.PCA.html#sklearn.decomposition.PCA.inverse_transform

Thank you!

The issue names no repository files or tests. Start by reviewing the UMAP embedding API and the linked scikit-learn PCA inverse_transform reference; done means providing a supported inverse operation from embeddings back toward the original data space, with behavior and limitations established.
