Compilation fails with GCC 13

[GaetanLepage]

When trying to install ale-py with GCC13 as a compiler, the build fails with several instances of such error:

note: ‘uint8_t’ is defined in header ‘<cstdint>’; did you forget to ‘#include <cstdint>’?

I guess that <cstdint> has now to be explicitly included: https://gcc.gnu.org/gcc-13/porting_to.html

Thanks for finding that @GaetanLepage, would you be able to submit a PR fixing the issue?

I guess that it would only boil down to adding a bunch of include <cstdint> at the beginning of the right files.
However, I fear that I won't have the time for this during the next few days...
