Adds a string to the details indicating the address with byte differences and the byte values.
@param p1Address the address to get the bytes for.
This address should be derived from program1.
@param addrLength the length of the address field.
@param mem1 the first program's memory for obtaining the bytes
@param mem2 the second program's memory.
