This script will download WebRTC resource files used for testing, like audio
and video files. It will check the current version in the DEPS file and
compare it with the one downloaded (kept in a text file in the download dir).
If there's a new version of the resources available it will be downloaded.
If the DEPS version is different than the one downloaded, the correct version
will be downloaded.
