Delayed retry in README leads to unexpected result about p-retry

[jdmarshall]

I was just trying to write a test and was surprised to find that my retry was taking almost exactly 1000 ms longer than I expected.

I don't think trying to adding an explicit delay to the onFailedAttempt() is the correct solution here. I think documenting the options pass-through to retry is the correct strategy. For instance:

pRetry(myFunction, { retries: 2, minTimeout: timeout, factor: 1 })

Thanks for commenting. That's a good point. I've improved the example now.

Additionally, because the retry module is not using arrow functions, it ends up rebinding 'this', which I didn't notice in my initial implementation, and so my delay function was getting undefined as an argument.

The way I'm suggesting avoids that problem, but you might want to work that into any other examples, if for no other reason to signal to people "hey this bit is tricky".
