[Feature request] Ignore files

[scinos]

It would be nice to have a way to fully ignore files that I don't want get linted/fixed (for example, a LICENSE file).

Maybe a <!-- eslint-disable --> at the top?

I was just looking for this.

@semantic-release/changelog uses @conventional-changelog/conventional-changelog to create a CHANGELOG.md file

However, that generated file fails linting.
semantic-release/changelog#84

It would be really helpful to be able to exclude this file, same as with out of box eslint-supported filetypes, without having to build up a global eslint ignore list
