Feature: trigger function when days, hours, minutes turn to 0

Or add the option to remove 0 days, 0 hours, 0 minutes automatically.

so:

0 days 0 hours 22 minutes 30 seconds

would be:

22 minutes 30 seconds

It should be a great option, if you want to contribute you're welcome 😃

That may be easly made by adding a new option like autoRemove: true. With default to false.
I suggest to add a parametric class to the main countdown element like -autoremove if set to true to easly update the countdown CSS in that case.

Then, most of the work is to implement conditional checks to hide unwanted elements.
