Describe the feature

Framed Blocks already supports Diagonal Fences and Diagonal Windows, so adding compat with Diagonal Walls would be cool

As much as I would like to support the full trio of Diagonal Thing mods, making Framed Walls support Diagonal Walls is unfortunately not feasible. The fences and panes are already pushing things with a very high blockstate count (which is a problem for both memory consumption and game startup time) and the wall would be significantly worse.
