Allow `ignore` to accept a function?

[cheapsteak]

Subject of the feature

I would like want to fine-tune the ignore section of a findAndReplace to ignore replacing things inside e.g. something that has a specific class name; would be nice if i could specify a function so i can customize whether to ignore a node

Problem

only being able to specify tagNames to ignore doesn't give me the granularity i need to ignore the things i want

Expected behaviour

I'd like to be able to pass in a function to ignore, e.g.

ignore: (node: Node) => boolean

Alternatives

Can't think of any

It may make sense to update hast-util-is-element to work more like unist-util-is. It’s probably what folks expect, and would automatically solve this issue.

I do wonder about what Object would mean though. Properties check maybe? isElement(node, {id: 'some-id'}). Or we can ignore that for now.

As long as it can support some kind of selector that's more specific than an entire HTML tag then that would work :)
