WIP Convert to ts

[devinrhode2]

Lot of work/cleanup to do here still. Just wanted to share WIP as I may not get back to this for a few weekends.

I was having a time with the types, so started inling all the functions, so see what the natural types are, convert/type case values to something better, than pass pure data into utility functions

Most recent commit is going to be the most interesting

Probably this should live along side some JS version, since likely whatever I come up with will be extra "typescript-y"
