Initialize using top-level await

[evelynhathaway]

I think it would be good to have a submodule that uses top-level await to halt code execution until the user or user agent accepts the Web MIDI API permission. I think it would be a bad idea to do this on the main module since it could be blocked for minutes.

Currently, the proposal for top-level await is at stage 2 and I don't know when/if support will come to Node.js.

Possible example of a wrapper that could use top level await to simplify implementation

@rocketry/plugin-web-midi/sync

import pluginWebMidi, {init} from "./index";

await init(); // will use default options

export default pluginWebMidi;
export * from "./index";

---

comsumer.js

import "@rocketry/plugin-web-midi/sync";
import rocketry from "@rocketry/core";

// Use Rocketry here without having to worry about making an async context
// Nothing past the last import will run until the permissions have been accepted/rejected

Looks like top-level await will experimental soon.
