// We have to use a different MsgPackSerializer for the browser, because msgpack5 depends on
// bl which uses some node globals if not correctly bundled.
// However, this will stop bundling from working correctly, as msgpack is always pulled in.
// So we don't export the msgpack serializer by default, but instead rely on ES6 modules.
