Describe the problem you'd like to have solved

This library is using an outdated version of lru-memoizer, which in turn has a dependency on lru-cache. The lru-cache version it is using is pretty outdated and is no longer compatible with new versions, as a result applications depending on packages that use different versions break when bundling them.

Describe the ideal solution

Ideally lru-memoizer would update its dependency on lru-cache to the latests version, but I opened this issue two weeks ago jfromaniello/lru-memoizer#32 and I'm not sure if thats going to happen.

lru-memoizer has been updated to version 3.0 which uses the latests lru-cache version, therefore it could be updated. Option maxAge has changed to ttl.
