This should make VSE code more readable and easier to understand from an outside perspective. The name was chosen to be `channel` rather than `channel_index` to keep things short and concise -- it should be clear based on the context whether we are talking about the strip's channel index (singular case, `Strip::channel` or `SeqTimelineChannel::index`) vs. the channel list (plural case, e.g. `Editing::channels`).
