v4.3.0

• fixed the return value "willPlayNext" if the "loopQueue" mode is enabled, if the queue is supposed to loop this means that the last song in the queue should have a "willPlayNext" value set to true and not false, as the next song after the last one in the queue will be the first song in the queue
• added two new methods, one to change the value of "loopQueue" (setLoopQueue) after player initialization and the second one is a getter (getLoopQueue) method to get the current value of "loopQueue"
• finally added some documentation to the players readme
