A configuration parameter which sets the debounce time in milliseconds for
the quantity controls built using the <ajax-cart-quantity> custom tag.
By default, the debounce time is 300 milliseconds.
Use the conf method of the liquidAjaxCart object to set
another value.
For example if you want the <ajax-cart-quantity> custom tag to start updating
the quantity without any delay, set the value to 0:
liquidAjaxCart.conf("quantityTagDebounce", 0);
