Include stdint.h in functions.cpp

Building on Linux (gcc 13.2.1, glibc 2.38, Linux-6.6.21-gentoo-x86_64) with the default 16bit branch, it errors out as follows:

Including stdint.h in functions.cpp allows the build process to finish successfully, generating a working libmasktools2.so (as far as I can tell, only needed mt_edge for now). Not sure whether this is the correct way to fix the issue; maybe some preprocessor logic which should automatically include stdint.h (or cstdint) does not work correctly with my system? If so, happy to provide additional info on the environment.
