Documentation for .set is wrong.

[mstade]

Hi! Lovely library, thank you for sharing it with the world!

The documentation for .set states:

.set(key, value, options?)

Set an item. Returns the instance.

(Emphasis mine.) This seems to be wrong – .set doesn't actually return anything. It would be rather handy if it returned the value though, it'd allow for things like:

const thing = lru.get(key) ?? lru.set(key, getThing())

Returning the instance would work too I suppose, it'd be a bit awkward but still:

const thing = lru.get(key) ?? lru.set(key, getThing()).get(key)

Either way, .set doesn't actually return anything so the docs seem to be wrong.

Fixed.

I'm open to adding a getOrSet() method.
