> The {{openFile()}} builder API lets us add new options when reading a file
> Add an option {{"fs.s3a.open.option.length"}} which takes a long and allows the length
of the file to be declared. If set, *no check for the existence of the file is issued when
opening the file*
> Also: withFileStatus() to take any FileStatus implementation, rather than only S3AFileStatus
-and not check that the path matches the path being opened. Needed to support viewFS-style
wrapping and mounting.
