Open a file compatible with the gzip program. Note that if a file is opened in append mode, a second gzip image will be added to the end of the file. The gzip standard defines that a file can hold multiple gzip images and inflating the file results in a concatenated stream of all inflated images.

Options are passed to open/4 and zopen/3. Default format is gzip.
