daq backend starts immediately in allinone launcher

[nzjrs]

or at least the accounting of when things occur is incorrect?

because of how the data_generator works, maybe we have to signal_new_playlist_item before the chunk is callback'd to the daq buffer?

  daq:
  - Delay-1s:

      amplitude: 0.0
      duration: 1000
      name: constant
      post_silence: 0
      pre_silence: 0
      sample_rate: 10000
  - Opto1090-9-1:

      amplitude_b: 0.0

      name: pulse
      post_silence: 1000
      pre_silence: 1000
      sample_rate: 10000

notice that in the toc file Opto1090-9-1 plays immediately after Delay

- {"item": "Delay-1s", "backend": "daq", "sound_output_num_samples_written": 0, "video_output_num_frames": 0, "daq_output_num_samples_written": 5000, "fictrac_frame_num": 4850}

actually everywhere. I guess we need to send this information from the SampleChunk (when we detect it changes)

I noticed this because of the incorrect buffer size for the output (5000) but it was nevertheless also fixed with chunk provenance in https://github.com/murthylab/fly-vr/commit/9d87ca8924328b5598e61789c31c35065f3e6885
