Feature request: Custom handler for ModuleDeployableRadiator animations

[Rodg88]

I have a part which is a deployable radiator with 3 subtypes, each with a separate mesh with associated animation. It mostly works, the different variants deploy with the correct animations, but the non-default variant's won't retract. I could set the radiators to non-retractable as a work around, but it'd still be broken in the VAB, where it'd still need to be retractable.

From my cfg:

	MODULE
	{
		name = ModuleB9PartSwitch
		moduleID = meshSwitchSide
		switcherDescription = Panel count
		switcherDescriptionPlural = Panel amounts
		affectDragCubes = False
		affectFARVoxels = False
		SUBTYPE
		{
			name = 2x
			title = 2 Panel
			primaryColor = #c7c7c7
			secondaryColor = #c7c7c7
			transform = 2PanelsBase
		}
		SUBTYPE
		{
			name = 4x
			title = 4 Panel
			primaryColor = #c7c7c7
			secondaryColor = #c7c7c7
			transform = 4PanelsBase
			MODULE
			{
			IDENTIFIER
				{
				name = ModuleDeployableRadiator
				}

			DATA
				{
				animationName = RadDep4
				}
			}
		}
		SUBTYPE
		{
			name = 6x
			title = 6 Panel
			primaryColor = #c7c7c7
			secondaryColor = #c7c7c7
			transform = 6PanelsBase
			MODULE
			{
			IDENTIFIER
				{
				name = ModuleDeployableRadiator
				}
			DATA
				{
				animationName = RadDep6
				}
			}
		}	
	}
