The decompression / compression happens inside a Web Worker, if the runtime supports it (browsers,
deno). The library uses native decompression, if supported by the browser
(via [DecompressionStream](https://developer.mozilla.org/en-US/docs/Web/API/DecompressionStream/DecompressionStream)), and falls back to JavaScript implementations otherwise.

The API is event-based, you will want to subscribe to some of these events:
