 * EAT-based hooking for x86/x64.
 * 
 * Big thanks to ez (https://github.com/ezdiy/) for making this!
 * 
 * Creates "hooks" by modifying the module's export address table.
 * The procedure works in three main parts:
 * 
 * 1. Reading the module's PE file and getting all exported functions.
 * 2. Finding the right function to "hook" by simple address lookup
