New Class property (vs older Type property) : Area generates StaticBody2D instead of Area2d

[yarrayunder]

Tiled version 1.9.2
Plugin version 2.3 (same with 2.4)
Godot version 3.4.5

**Issue description :
After Tiled 1.9x, Godot creates "StaticBody2D" objects instead of "Area2d" objects like previously.
In Tiled 1.9.2, uppon re-opening previously created maps, object layers that had objects with "type" = "area" are converted to "class"="Area". The "Type" property is lost.

Tiled importer plugin now creates StaticBody2D.new() instead of Area2D.new() because it relies on the "type" property instead of the new "class" property. (var body = Area2D.new() if object.type == "area" else StaticBody2D.new())

Steps to reproduce

In Tiled 1.9x, create object layer with rectangle shape with class property = "area". Import in godot : Godot will crete a "StaticBody2D" instead of "Area2d".

**Temporary fix

I modified "tiled_map_reader.gd", and changed this line :

var body = Area2D.new() if object.type == "area" else StaticBody2D.new()

for this :

var body = Area2D.new() if object.type == "area" or object.class == "area" else StaticBody2D.new()

Thanks !
