Add a way to ignore custom model data of items

[Folas1337]

Feature description

My server uses custom model data to create different version of armor, weapons and tools but unfortunately the experience sources do not take those into account so if you enchant one of those things with custom model data on it, it'll not yield any enchanting experience for example.

So I am hoping for an option like "ignore_custom_model_data" so I could simply add that to the sources that already exist and then I could make as many custom items as I want without having to worry that it would not give any skill experience.

Additional context

We've already talked about this on Discord here: https://discord.com/channels/732657582313046027/1224467235754737825/1330634084644425808 where it sounded like Archy would try to add a feature like that.
