Component groups cannot be reordered through terraform

[XaF]

It seems that with #4 it is impossible to provide an order for the components when defining a component group.

I would like to be able, with terraform, to define the order in which my components appear for the component group.
When passing a list to the component group for the components it contains, that list now using a TypeSet means that the components won't be reordered as expected. There is also no alternative to indicate the order should be enforced.

A ordered option could solve the issue for instance.
