Observable for renoise.song().transport.playback_pos.sequence?

Is it possible to get notified when the playback_pos.sequence changes? That wouldn’t be a frequent event… Can’t seem to find it in the current API. Can check for that on timer, but feels hacky…

use app idle observable to have it checked in ‘ticks’ or if it may suffice, the formula device, it has a position in sequence parameter

Here is how I did it, but I might be using the new ObservableBang object in the future.
