small fix for ReadXenium

[alikhuseynov]

Hi, this is just a quick fix for ReadXenium to always return dataframes when sapply is used.
..see issue #8265
thanks

@AustinHartman any update on this? Would be awesome to get it merged when you've got some cycles. Also about to tag you on another Xenium-related PR

@jsicherman I was thinking, probably it would be better to make reading transcript coords optional, such that users can decide themselves if to load molecules or not. I added add.molecules for readVizgen some time ago. Since those coords are not used at all in any analysis in Seurat, only for visualization.

Added in #8605 :)

Hi @dcollins15 and @Gesmira. We have a few PRs to improve Xenium support in flight -- this one and #8605. Austin seems to be offline these days. Who should we ping for help getting these merged?
