These are technically pointers, so lets type them as such.

This will read the data from the sd card, copy it to the originally linked address (no relocation), then execute it. I am lazy and wrote it in C using weird function pointer casting but this would probably be more efficient if it were to be written in assembly instead. The test program simply returns 'A', but that is enough to prove that it is actually running.

These were used to help understand the o65 file format, but are not needed and shouldn't have been commited anyway.

These are object files still, which means we do not want to track them.

I had used these to try and help figure out the structure of the o65 file but this is not needed anymore

Prints out the options now too.

Prints out information about the first file found on the SD card, if it is an o65 file.

This adds a test program which can be loaded and executed by the host. It simply returns a value in the `a` register. The linker script is modified so that it will output an o65 file, and the memory sgments are changed as well. There is no STARTUP segment defined, so it uses the default `none` crt0, which sets up the stack and does initialization and deconstruction. The Makefile is modified to not turn the output into an intel hex file, and instead keep it as the o65 file.

These can be used to read and parse o65 files.
