Here is my solution
At first it was pretty slow (~6s for part2), and I naively fixed it via memoizing the result of count_paths with an Agent.
Only then I realized that performance problems were due to the fact I was using a regex for the “small cave” check 
On the bright side I learnt how to profile elixir code

My recursions are getting better, but it’s still not easy
