Describe the Bug

If the above occurs, the player and is kicked out. I've noticed a problem with package handling when creating a scoreboard. Under com.r4g3baby.simplescore.scoreboard.handlers.ProtocolScoreboard, the createScoreboard method should not be modified with integers in the createScoreboard method, which is byte related.

Maybe it could be modified like this, but I don't know kotlin.

            packet.modifier()
            packet.strings.write(0, getPlayerIdentifier(player)) // Objective Name
            packet.integers.write(0, 0) // Mode 0: Created Scoreboard

Just change it to the above code.I try to tested it.
