Feature Request: Adding an optional cleanup function to allow async polling to be cancelled

[louisnow]

Here's a question about something similar
I can make a pull request with an optional cleanup function and it would include no breaking changes. The implementation would be similar to this

Ideally this utility would accept an options object with delay as a key but this could be a potential pitfall. Every render would cause the interval to be reset if the options object is not defined with a useState or is defined in the function component directly.
