Cleaned up code of ctypes_and_api. will serve as the example for the implementation in the python-binaryc

made script to write function pointer to char and convert it back to a function pointer in a different function

created some cython DLL reading, i'm able to fetch the memory adress, but not yet finished with the ptr -> int -> ptr conversion. also updated readme

updated ctypes attempt. next step is trying to figure out how to pass a pointer through something via something
