Collisions masks are not always imported

[jeangit]

Hello,

I've defined collisions masks in my Tiled file.
When there are defined as rectangles or circles, they are imported (circles are transformed to capsules, as you warn in your ReadMe).
But when they are either polygon or polyline, they are not imported properly. I tried to draw them in clockwise order, as you mention it in the documentation.

I've made a super simple project for showing this:

(password is godotgodot)
In the project above, collisions defined with rectangles are imported in Godot (horizontal and vertical road tiles).

You can see a screenshot of a collision not exported here:

Thank you!
