Files stored on OSF can be downloaded locally by providing an
osf_tbl_file that contains the OSF file of interest. If the
osf_tbl_file contains a directory, a zip file containing the
directory's contents will be downloaded.
By default files are downloaded to your current working directory with the
same filename used on OSF. The path argument can be used to specify a
different destination and, optionally, a different filename for the
downloaded file. Note, the directory portion of path must reference an
existing directory.
