mono parameter to the Audio feature is missing
Hey,  we removed the misleading passage in the docstring and enabled support for `num_channels` as torchcodec does thanks!
According to the docs, there is a "mono" parameter to the Audio feature, which turns any stereo into mono. In practice the signal is not touched and the mono parameter, even though documented, does not exist.
