Add option to not translate known RAM addresses to aliases

[chip8fan]

It would be better for the purposes of analysis if the .asm file had known addresses than if they had variables that basically translates to gibberish.

Can you give an example of when this is needed?

Any time somebody would do an in-depth disassembly of a certain game. It would be impossible for nesgodisasm to simply generate the code for the programmer without the programmer having to do work to make the code human-readable, but it would only take more work if there was no option to keep the known RAM addresses.
