// You may also wish to take a look at the guide I made about this program:
// https://gist.github.com/101arrowz/253f31eb5abc3d9275ab943003ffecad
// Some of the following code is similar to that of UZIP.js:

// Sometimes 0 will appear where -1 would be more appropriate. This is because using a uint
