ha! basemeow works! somehow!

it doesn't handle underflow in the arithmetic encoder yet so it crashes on some inputs, but heh, i am happy it at least works

$ echo "hi fedi fwens 😁 ur all ghey" | cargo -q run -- encode

i really need to clean it up... Frac is such a leaky abstraction right now

you can see how much i struggled from the amount of tests

bit twiddling is annoying

it will become incompatible once i change the corpus to include all of fedi's meows
