* Creates a debounced function that delays invoking `func` until after `wait`
* milliseconds have elapsed since the last time the debounced function was
* invoked. The debounced function comes with a `cancel` method to cancel
* delayed `func` invocations and a `flush` method to immediately invoke them.
* Provide `options` to indicate whether `func` should be invoked on the
* leading and/or trailing edge of the `wait` timeout. The `func` is invoked
* with the last arguments provided to the debounced function. Subsequent
* calls to the debounced function return the result of the last `func`
* invocation.
*
* **Note:** If `leading` and `trailing` options are `true`, `func` is
* invoked on the trailing edge of the timeout only if the debounced function
* is invoked more than once during the `wait` timeout.
*
* If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
* until to the next tick, similar to `setTimeout` with a timeout of `0`.
