Overview
This updates the file format and the in memory structures so we can mmap the IRData and RAData from the file, instead of having to read it. This also introduces a sorted array for binary searching the file, which can also be mmap'd.
This makes it possible to load AOTIR files very quickly, and in fairly constant time. It effectivelly can pull a few fragments from a huge (6GB+ tested) aotir file without taking 2 seconds to load.
