Subject: [PATCH] feat: add bundle with msgpack parser

Pros:

- events with binary content are sent as 1 WebSocket frame (instead of 2 with the default parser)
- payloads with lots of numbers should be smaller

Cons:

- no IE9 support (https://caniuse.com/mdn-javascript_builtins_arraybuffer)
- a slightly bigger bundle size (61.1 vs 59.9 KB)
