Current Behavior

When we use the annotations to set argument, the default value from kotlin declaration is not supported.

With the current system, the command bellow cannot be executed when the player doesn't define the values for args :

@CommandMethod("test [x] [y] [z]")
@CommandDescription("Test command")
suspend fun testCmd(
        player: Player,
        @Argument("x") x: Double = player.location.x,
        @Argument("y") y: Double = player.location.y,
        @Argument("z") z: Double = player.location.z
) {
 println("parameters : $x $y $z")
}

If the user doesn't add an argument, a null value will be used to set the arguments.

Effectively, in the @Argument, there is a String to define the default value, but in the most cases, it's not enough.

Expected Behavior

The command defined above can be used if the user writes :
/test
/test 1
/test 1 2
/test 1 2 3
