It would be nice to easily compress data we are writing to tags but an async streams doesn't work for us as all data needs to be ready when the write happens.
It is probably going to be something like
```
let data = ...
const cs = new CompressStream();
const readable = new Blob(data).stream().pipeThrough(cs);
while (true) {
const { value, done } = await reader.read();
if (done)
break;
out.push(value);
totalSize += value.byteLength;
}
const concatenated = new Uint8Array(totalSize);
let offset = 0;
for (const array of out) {
concatenated.set(array, offset);
offset += array.byteLength;
}
return concatenated;
```
