List of Arturo code golfs

So far, these are written using Arturo v0.9.80. Of course, the upcoming v0.9.82 and beyond will present some obvious improvements, so please keep that in mind. Some of these have been improved over time, indicated by strikethrough of the byte count. Note the difficulty rating measures how hard a problem was for me to golf, not necessarily how difficult it was to solve.
