Given command line argument for file in standard format (map of RAM address -> 32-bit hex ASM instruction) and a command line argument for .iso file, overwrite the DOL of the .iso so the proper values are given at each address.

Test this works in Melee by injecting

game should write 5342 to address 0x80001800

wiimake-isotool invalid_file.ext crashes badly

E.g., entering something like wiimake-isotool (no arguments) or wiimake-isotool /path/to/iso (one argument) gives a segmentation fault. Help messages are only displayed when providing something that's not a proper input, e.g., wiimake-isotool /path/to/not-an-iso or wiimake-isotool /path/to/iso --not-an-option.

The number of lines needed to be injected is calculated only from user provided code. Additional code (that will be injected) from libraries and .data sections must be accounted for.

Because object files need to be in unique sections, the normal powerpc-eabi-gcc-ar function is not sufficient. We need an additional call to powerpc-eabi-gcc-objcopy to rename sections.

branch to this function in stack_setup instead of doing it manually every time

Have some system in place for restoring an .iso file to a previous saved point.

i.e. Save the addresses in the current region of memory available for editing
