Mark Integer::divides as deprecated.
Resolves #41.
Hey, congrats, you're the first contributor that I've had to manually approve for GitHub Actions. :/
But I expect this will fail on older Rust, since this crates tests all the way back to 1.8, and #[deprecated] wasn't stabilized until 1.9. It's also a required method (though it should probably forward to is_multiple_of), so the deprecation warning would be forced on everyone who implements the trait as well.
Sorry I didn't know that #[deprecated] can't be used in 1.8.
So should we leave it until the min rust version is bumped?
And should we make an fallback to is_multiple_of to make it as provided method?
We have since bumped to 1.31, and I just added the default fallback as you suggested.
