64-bit support

[austenadler]

@hfutrell, I ported FMOD to OpenAL and compiled the game for Intel 64-bit which also runs on new ARM chips: https://github.com/austenadler/Argonaut-2149/tree/feature/openal

If you like this solution, let me know if you want me to make a PR back to this codebase (maybe in a new branch called OpenAL?) so people can play this game on modern computers!

wow! Yes, put up a PR and if it compiles and runs I will accept it into the main branch.

Thanks! I suggest if you do merge #2, you take a backup of the current master though. I haven't written ObjC before so the code isn't super great. Specifically:

1. The missile sound is quieter in this version, and I'm not sure why
2. There are minor memory leaks introduced by my usage of OpenAL. There are some in the original game too, so I figured it isn't the biggest deal. Just a few NSStrings every time you start a new game or load a game
3. I couldn't find a minDistance equivalent in OpenAL, so I left that out

Everything else works fine! I compiled and ran it (you can download here) on an Intel 64-bit and M1 chip Mac and it ran perfectly fine.
