Transfer feature-level metadata from SingleCellExperiment in as.Seurat.SingleCellExperiment function

[lianos]

Currently (Seurat v4.0.0, SeuratObject v4.0.0) there is no feature-level metadata that transfers over to a Seurat object from a SingleCellExperiment when we call seu <- as.Seurat(mySingleCellExperiment).

I'm not very familiar with the Seurat codebase and the structure of the Seurat object itself, but it looks like injecting this code chunk in between lines 1072 and 1073 here might do the trick:

assays[[1L]] <- AddMetaData(
  assays[[1L]],
  as.data.frame(SingleCellExperiment::rowData(x), row.names = rownames(assays[[1L]])))

Thank you for your suggestion. I added the code snippet and will likely be an update in a later release of Seurat.
