feat(misskey-js): allow setting binaryType of WebSocket connection

[cannorin]

What

This PR allows developers who use misskey-js to customize binaryType of the underlying WebSocket connection when using the streaming API.

Why

I wanted to use this library on bun to create a bot application with streaming capability.

However, bun does not support WebSocket connections with binaryType set to blob (probably just yet), which happens to be the default value.

See: oven-sh/bun#8721

Additional info (optional)

I'm not very sure if testing this over a mocked WebSocket server (new WS('wss://misskey.test/streaming')) would be helpful, as what really matters here is whether the real Misskey servers accept WebSocket connections of arraybuffer binary type.

As far as I can test, it is working without any issues when connecting to my own Misskey instance.
