Add a way of clearing the event listeners array and remove by ID

Feature request

1. Add a method to remove every event listener on the timer (eg. myTimer.clearEventListeners())
2. removeEventListener works by using indexOf() with a function, which can be unusable if using generated arrow functions. This could be solved by allowing an optional id to be passed along on addEventListener, which can later be used to identify the listener to be removed (eg. myTimer.removeEventListenerByID('secondsUpdated', 'myListener1')). If two listeners are added with the same id, the second should override the first

Looking at the code changes needed for this it don’t look like they should be too big. I may have some time to submit a PR if you need contribution
