Description

In an upcoming version of readr, read_csv() and friends will support vectors of multiple file paths. Consider adding support for this to the arrow::read_*() functions. In the as_data_frame = FALSE case, consider whether the result should be a Table or a Dataset and whether the user should be offered a choice of which, and if Dataset, consider whether there should be options for partitioning.

Alternatively we might add support for vectors of multiple file paths to arrow::open_dataset(), and note in the read_*() function docs to use open_dataset() for this purpose.
