Function playMidiHosted

playMidiHosted(file: MidiFile, options: HostedMidiOptions): HostedMidi
Plays a MIDI file through a synthesis core that runs off the main thread: builds an AudioCoreHost (a worker where one exists, the main thread otherwise, mode: 'auto' unless told), queues the file's messages on it and hands its output to a StreamChannel. A core too heavy for the frame (several voices of a modelled instrument) then costs the frame nothing; where only the main thread exists the sound is the same and host.stats().mode says so.
Parameters
- file: MidiFile
- options: HostedMidiOptions
Returns HostedMidi
Example
```
import { StreamChannel, parseMidi, playMidiHosted, type AudioCore } from '@datamoc/mwg/audio';

declare const context: AudioContext;
declare const midiBytes: ArrayBuffer;
declare const factory: (rate: number) => AudioCore;

const running = playMidiHosted(parseMidi(midiBytes), {
	sampleRate: context.sampleRate,
	factory,
	channel: new StreamChannel(context),
});
console.log(running.host.stats().mode);
```
