Ability to set playhead for PlaybackProcessor

[jtag05]

I'm curious if there is a way to set the playhead for a PlaybackProcessor in order to only render a specific chunk of an input file after running it through a set of processors that require the full original input.

I think PlaybackWarpProcessor has better support for this. You could follow this example

DawDreamer/tests/test_playbackwarp_processor.py

Line 113 in 1e15527

drums.set_clip_positions([[0., 4., 0.], [5., 9., 0.]])

but set
drums.warp_on = False It should be off by default if there's no .asd file.
If you did
drums.set_clip_positions([[4., 9., 0.]])
it would mean start using the audio file's audio at 4 beats into the rendering. You'll stop hearing the audio at 9 beats (so duration of 5 beats). The third value 0 is not used yet in this situation because warp_on is False. I have to make a better decision about what it should mean. It should probably be an offset measured in seconds. Whereas if warp_on is True it's supposed to be an offset measured in beats like the first two values.
