feat(imports/marker): Added invert property (#4)

MarkerType alias was replaced for an enum.
The type property in MarkerProps class is now optional, MarkerType or an integer (UpsideDownCone if missing).
The properties inside color are now defined as integers.
Added invert property, documented by CFX as drawOnEnts.
Added marker_mt metatable that stores default properties and draw method.
