impl Debug for LruCache

[thomcc]

Compatibility with lru-cache crate (also just generally a nice to have thing).

Yeah this makes perfect sense, and I agree with .rev() to show the most recently used entries first.

I think LinkedHashMap is also missing a Debug impl and needs it? I'll merge this and then add that as well.

Edit: oh it's there I'm just blind :/

Yeah, I checked for this too, it's buried a bit lol (impls tend to get this way in data structure crates tho).

It would be nice if you cut a release but isn't that big of a deal since it turned out it was only needed for a non-public type.

Actually I was planning on doing this, but in reviewing the Debug impls I noticed that the trait bounds were way too strict, and that pulled a thread of relaxing the bounds on various IntoIterator impls, iter methods, etc.

I think I got it though, and pushed d9b5a7e, so I think I can make a release now.
