Cast to int format error v2

[shewitt-au]

Another attempt at a fix for Cast to int format error (Format function no longer accepts enums) #166

Took me a few goes to get this. In the end it was pretty simple. Hope it works. It does for me.

The usual disclaimers. I don't know the code base well, etc...

It does smell a bit hacky, but by far the the simplest solutuon out of the ones I tired. Perhaps a better one would be to use enable_shared_from_this on the Pattern class. This would requite that Pattern is mangaged be a shared_ptr.

I have added as PR for second method. I prefer this one, although both work.

I actually wasn't aware of std::enable_shared_from_this! I believe that would actually solve our issue entirely. Let me play around with that a bit
Thanks a lot!

I'm about to push a PR. Waiting for all checks to pass.
