Description Arguments

This is a datastructure that stores the location of a CoxpresDb archive and the relative paths of all subfiles within that archive. If the archive is compressed, on construction of CoxpresDbAccessor a temporary copy of the uncompressed archive is constructed. So construction may take a couple of minutes depending on the size of the archive. You may want to wrap a call to this function in a future() block.

`archive`	The path to a CoxpresDb archive (either .tar.bz2 or .tar).
`archive_uncompressed`	The path to an uncompressed copy of the CoxpresDb archive.
`file_paths`	The relative paths of all file present in subdirectories of the archive. As a data-frame of 'gene_id' -> 'file_path' pairs.
