After speaker.end(), coreaudio.c continuously reports buffer underflow

[cjheath]

(Sorry for no isolated test; this program requires a HackRF. I didn't write it and don't know Node well enough to trust myself to write an isolated example)

In the FM receiver here, when the receiver is interrupted with SIGINT, it calls speaker.close.

The coreaudio module then continuously reports the following error, instead of just stopping output:
[../deps/mpg123/src/output/coreaudio.c:81] warning: Didn't have any audio data in callback (buffer underflow)

I can't see where the problem lies or I would offer a PR to fix it.

I forked the repo to include both @zackradisic's patch (#18 (comment)) and the 12 commits to main since then: https://github.com/JasonBenn/node-speaker

Update your dependency to "speaker": "github:JasonBenn/node-speaker", and reinstall packages to use it.
