run coros utility func

[wild-endeavor]

Hi Team. I'd like to use the run_coros_in_chunks function. I understand there's some callback functionality in there, but can we make it a public function (just no _)? Maybe the public function always just hardcodes the noop callback?

Thank you.

This being python, the "_" really means "not designed for end-users". In a library like this one, most people who look at the code are NOT end-users, but developers of other libraries. In this case, it specifically interacts with fsspec's internal loop/thread, so I would want to mark somehow that it's an expert-level function.

just hardcodes the noop callback

NoOpCallback is already the defeault - do youn mean something else?
