Return UMAP model with RunBBKNN

[edroaldo]

Hello, thanks for developing this package!

Can you please let me know how to return the UMAP model after running RunBBKNN?
This would substantially facilitate reference mapping based on an a BBKNN-generated reference.
I was trying to integrate this into the Seurat workflow but I had no success so far.

Something like this (return.model parameter)
seu <- RunUMAP(seu, reduction = "harmony", dims = 1:50, reduction.name = "umap.harmony", return.model = TRUE, umap.method = 'uwot')

Thank you!
