Export feature loadings in anndata2seurat

[Zepeng-Mu]

Hello,
It seems that currently anndata2seurat does not export feature loadings from PCA.

sceasy/R/functions.R

Line 461 in 0cfc0e3

loadings = new("matrix"),

I think this data should be in the anndata and it would be great if this could be exported. In some Seurat analysis like multi-modal integration, it uses this information in ways like rownames(seuratObj@[email protected]). Not having this from anndata means that pca pre-calculated by scanpy cannot be used.

Thanks!
