Usage: haskell-chip8 ROM_FILE_PATH [-s|--max-stack-size MAX_STACK_SIZE] 
                     [-t|--tick-rate TICK_RATE_INTERVAL] [-v|--verbose]
  emulate execution of a CHIP-8 rom

Available options:
  ROM_FILE_PATH            path to rom file
  -s,--max-stack-size MAX_STACK_SIZE
                           max stack size / recursion depth (default: 50)
  -t,--tick-rate TICK_RATE_INTERVAL
                           tick rate in microseconds per instruction
                           (default: 2000)
  -v,--verbose             enable debug logging if flag is set
