Add a timeout function wrapper

[empz]

A timeout function that takes an async function and a timeout number and will throw an error if the passed function takes longer than the timeout. Maybe even use tryit under the hood to return error.

const [err, data] = await timeout(5000, async () => { 
  // long running function
});

// err is an `Error` if the function doesn't resolve in less than 5000ms (maybe a custom `TimeoutError`?)

if (err instanceof TimeoutError) {
  // handle timeout
}

Not sure if the same function could be used for regular (non-async) functions too.

Hello @empz! The Radashi fork has a timeout function in the works (radashi-org/radashi#250). You can use it today by installing radashi@beta. ✌️
