sparseq ticks timed at at loop edges not included in the loop

[bthj]

If el.sparseq includes seq elements with tickTime set to the loop start or end points, then those are not included in the loop sequence, while elements with tickTimes that fall within the loop edges are included.

This loops:

    return el.sample(
      {path: 'synth:0'},
      el.sparseq({
        seq: [
          { value: 1, tickTime: 1 },
        ],
        loop: [0, 500]
      }, 
      el.train(100), 
      0),
      1,
    )

while this does not:

    return el.sample(
      {path: 'synth:0'},
      el.sparseq({
        seq: [
          { value: 1, tickTime: 0 },
        ],
        loop: [0, 500]
      }, 
      el.train(100), 
      0),
      1,
    )

Just after submitting this issue, I see that the issue is solved on the playground at the above links.

But I noticed this in @elemaudio/web-renderer 4.0.3 and temporarily added a workaround in a thing I was trying.

Thanks for filing! I see the issue in the playground links and it seems to reproduce in 4.0.3 for me as well. I suspect there's an off-by-one in the sparseq code. I will look to get a fix in asap!
