Use native chrome decompression

[lpatiny]

We should check if DecompressionStream exists and use it if available

Problem ... it will become async but we could win up to a factor 2.

async function DecompressBlob(blob) {
  const ds = new DecompressionStream('gzip');
  const decompressedStream = blob.stream().pipeThrough(ds);
  return await new Response(decompressedStream).blob();
}
