// MemoryWatcher reads a file containing in-game memory addresses and outputs
// changes to those memory addresses to a unix domain socket as the game runs.
//
// The input file is a newline-separated list of hex memory addresses, without
// the "0x". To follow pointers, separate addresses with a space. For example,
// "ABCD EF" will watch the address at (*0xABCD) + 0xEF.
// The output to the socket is two lines. The first is the address from the
// input file, and the second is the new value in hex.
