Facade_Engine: Account for doubled up edges and check adjacency psi values for UValueOpeningsSAM Method

[enarhi]

Description:

The UValueOpeningsSAM method currently accounts for psi value-based frame loss independently for each frame edge, meaning adjacent frame edges are double counted. In addition, there is no existing check to ensure adjacent edges have the required matching frame psi values assigned.

Steps to reproduce:

Run the method on multiple openings with an adjacent edge.

Expected behaviour:

Result U Value accounting for shared frame edges, and user friendly error handling when adjacent edges do not have matching values.
