Create client-side friendly version of cpu throttle

[soapdog]

On this ssb message Andre Staltz announces a nifty little module called pull-cpu-throttle which I'd love to use in Patchfox. Unfortunately the browser doesn't support process.*, so another implementation is needed.

From a msg exchange on that thread, Staltz mentioned:

"@soapdog, you need to have something that tells you how much CPU is being used. Maybe requestIdleCallback? You can fork the codebase, it’s tiny. Or you can use pull-pausable directly, plus your own logic"

Which I plan to try once patchfox solidifies a bit more.

I don't have the bandwidth to do this.
