Losing graphic control extension for some frames

[jeetiss]

this gif contains 2 application blocks in a row, so first frame lose gce info and renders without transparency

I fix it on my side, with this workaround

const validateAndFix = (gif) => {
  let currentGce = null;
  for (const frame of gif.frames) {
    currentGce = frame.gce ? frame.gce : currentGce;

    // fix loosing graphic control extension for same frames
    if ("image" in frame && !("gce" in frame)) {
      frame.gce = currentGce;
    }
  }
};

but I think that a better way is fix this library or improve loop condition for frames inside https://github.com/matt-way/jsBinarySchemaParser
