Can't use createSpeech without saving to file.

[allComputableThings]

OpenAI.instance.audio.createSpeech insists on saving the result to a file.
It doesn't seem necessary (and is problematic for me). (Perhaps it could return the result if the file and directory were null?)

Looking at its implementation, I also can't directly call
await OpenAINetworkingClient.post
... since it is not exported.

Yeah, this makes sense, but what would be the expected behavior here?

I'd like to invoke it using a BytesSource: https://pub.dev/documentation/audioplayers/latest/audioplayers/BytesSource-class.html

would that be possible?

I have opened a PR that hopefully adds this: #177

I'm new to Dart so please check it over, it should work however.

Edit: works, example code in PR
