RFC: Replace Haskell CIS (2016) with MOOC variant from Aalto University

**Problem:** * OSSU lists [Introduction to Haskell](https://www.seas.upenn.edu/~cis1940/fall16/) to teach Haskell topic, but there exists a higher quality course that covers the same material. **Duration:** 1 month **Background:** The [Introduction to Haskell](https://www.seas.upenn.edu/~cis1940/fall16/) is starting to show its age. In the intervening 7.5 years since the course was taught.
