Point objects: rotation not imported

[mrgkingcs]

Plugin version
2.3

Issue description
Rotation is not imported for Point objects. It is useful for game logic.

Steps to reproduce

1. In Tiled, add object layer.
2. Add Point to layer.
3. Click on rotation button to change rotation of point
4. Import tilemap to Godot

Sample map or tileset
TestTrack.zip

code fix
Insert at line 361 in tiled_map_reader.gd:
if "point" in object and object.point:
var point = Position2D.new()
if not "x" in object or not "y" in object:
print_error("Missing coordinates for point in object layer.")
continue
point.position = Vector2(float(object.x), float(object.y))
if "rotation" in object:
point.rotation_degrees = float(object.rotation)
point.visible = bool(object.visible) if "visible" in object else true
...

Hmm, in fact in Tiled, point objects can't be rotated. I guess this is something I've disabled after this issue was opened (though they could not be rotated already when mapeditor/tiled#1799 was merged).

I can see it has its uses though, as demonstrated by the provided example, so maybe it's worth properly supporting at some point.
