The debouncer is partly based on https://github.com/bep/debounce.
context.Context was added in order to ensure passed function would be called even if the program is stopped
debouncer := NewDebouncer(context.Background(), 80*time.Millisecond)
debouncer.Add(myFunc)
debouncer.Add(myFunc)the debouncer will run the last function on <-ctx.Done
throttler := NewThrottler(context.Background(), 80*time.Millisecond)
throttler.Add(myFunc)
throttler.Add(myFunc)the throttler will not run the queued functions on <-ctx.Done
