Parse a provided string as a `ListingTableUrl` A URL can either refer to a single object, or a collection of objects with a common prefix, with the presence of a trailing `/` indicating a collection. For example, `file:///foo.txt` refers to the file at `/foo.txt`, whereas `file:///foo/` refers to all the files under the directory `/foo` and its subdirectories. Similarly `s3://BUCKET/blob.csv` r
