[FEATURE] add a config to read files from optifine/* directory

[MeeniMc]

Version

0.3.3

Issue

The CEM addon doesn't read the entity models from the optifine directory, but from another directory instead. The models themselves are (as far as I tested) compatible, so the only impediment to using existing resource packs is that one has to convert them. The task is not hard, but it is an annoying extra step.

Proposed enhancement

The CEM mod would also load models from the optifine/* directory. This could be an optional behavior that could be set on (or off? depending on how much incompatibilities are expected to be an issue, it maybe would make sense for this to be default behavior) with a config file/modmenu config.

This would actually probably be easier to implement than I thought it would, I'll look into it. I'm not experienced at making modmenu config screens though so it will be a little while

Also I love the formatting you used for this issue, very clear and concise!
