OctonetData: Use hash for channel nativeId

We previously assumed that the channelId provided by the Octonet would
only contain numbers and colons, which unfortunately is not true. The
satellite names could contain arbitrary characters, which then caused
the conversion to a numeric value to fail, stopping channels from being
distinguishable. This caused all EPG events to be mapped to the first
channel.
