2015, day 16-25 (first completed calendar!) (#11)
* Solve 2015:16 "Aunt Sue"

* Make 2023:08 future compatible

Code used to work with another version of python.

* Solve 2015:17 "No such Thing as Too much"

* Solve 2015:18 "Like a GIF For Your Yard"

Also solve 2015:06 just in case, was just a ref
in the end.

* Solve 2015:19 "Medicine for Rudolph"

* Solve 2015:20 "Infinite Elves and Infinite Houses"

* Solve 2023:21 "RPG Simulator 20XX"

* Solve 2015:22 "Wizard Simulator 20XX"

* Solve 2015:23 "Opening the Turing Lock"

* Solve 2015:25 "Let it Snow"

Wrote p2rc and rc2p just for academic purposes.
Puzzles could be solved anyway.
