`obj`	A `QFeatures` object
`i`	A `numeric()` or `character()` vector indicating from which assays the `rowData` should be taken.
`vars`	A `character()` vector indicating which variables from the `rowData` should be extracted.

Along with the reuired rowData an additional .assay variable is created and holds the assay name from which the metadata was taken.

A DataFrame object with the rowData row-binded over the required assays.
