Title: Start of moving opcodes to storing output in a string

Started with the operation ORI. It stores addresses of strings that will be concatenated to give the final output.

IMPORTANT CHANGES
- A5 is used to traverse the output string
- The addresses of the output string start at $5000
- A6 stores the end of the output string

All of the other operations should still work, as I made new functions for ORI to call.

DATA outputs aren't printing the address now.. Forgot I changed that. I figured we can print the address no matter what, so if we have to scrap the output string because of an error in the operation, we can just print DATA.
