Added debouncer feature

[malcommac]

Implement debounce features using Repeater class as core.
The debounce function is an extremely useful tool that can help throttle requests. It is different to throttle though as throttle will allow only one request per time period, debounce will not fire immediately and wait the specified time period before firing the request. If there is another request made before the end of the time period then we restart the count. This can be extremely useful for calling functions that often get called and are only needed to run once after all the changes have been made.

Example:

let debouncer = Debouncer(.seconds(10))
debouncer.callback = {
	// your code here
}

// Call debouncer to start the callback after the delayed time.
// Multiple calls will ignore the older calls and overwrite the firing time.
debouncer.call()
