As mentioned in #134.

I'm not convinced about this. Let's discuss.

1. I'm not sure if the types have much value after this change. It's not going to help interoperability for someone using this in TS to be able to pass the wrong things in, even though the spec allows it.
2. Is any correct here? Object wasn't right.

It's not going to help interoperability for someone using this in TS to be able to pass the wrong things in, even though the spec allows it.

But aren't cores used for getting editorconfig options, rather than setting them? The change I suggested encourages developers to check the values instead of making assumptions
