hark the hoarding dragons roar

glory to vee oh point four

A pre-Christmas release with questionably but snappily named "hoards" where you can stash mutable data, as well as some quality of life stuff.

This was mostly driven by Advent of Code 2018. Yes v0.3 is sketchily retroactively added for the sake of the silly titular rhyme, but, well, it's the holiday season and I'm having fun.

(Wow I am messing with tags so hard to make the stupid rhyme happen >.>)
