Multi-mst

- Added a nearest-neighbour descent based variant for the k-MST algorithm. This version creates approximate k-MSTs and is much faster on datasets that do not behave nicely with KD-Trees. The compute time and accuracy are evaluated in new benchmark notebooks.
- Keyword arguments for UMAP are no longer taken from `**kwargs`. Instead use the named `umap_kwargs=dict(...)` keyword argument.
