Major API update to support multiple down-stream tasks. The classes now only construct the manifold models. Member functions are added to compute `umap` layouts or detect `hdbscan` clusters from the manifold. Especially the approximate nn-descent-based k-MST can speed up computing `hdbscan` clusters on high-dimensional data.
