Hi there

The current node-lru-cache v7.4.0 mentions an option: "updateRecencyOnHas". Is this actually implemented? A search shows "updateRecencyOnHas" only present in the readme, and the code doesn't mention it: https://github.com/isaacs/node-lru-cache/search?q=updateRecencyOnHas

I ran into this when upgrading for v6.0.0 to v7.4.0, when tests I have that assume this behaviour broke.

Many thanks for a useful library

Greg
