Make "_network._reset_topology_reduction_specifications()" a public method

I am following this example How to Generate Stable Starting Values to generate stable starting points and make the heat pump calculation converge.

I was successful, so perfect!

However, I was wondering why, after a failed calculation, we have to run the method nw._reset_topology_reduction_specifications() (where nw is the network from the example). Secondly, is there another way to perform this reset since the method above is not intended to be used outside the object (it is protected)?

Thank you!
