Support gcc13+

[george-pippos-qb]

Trying to compile this with gcc13 (and newer versions of clang) cause errors like the below due to include file resolution changes.

cryptolens-cpp/src/LicenseKeyInformation.cpp:21:3: error: 'std::uint64_t' has not been declared
   21 |   std::uint64_t sign_date,
      |   ^~~

The scope of changes required is just to add #include <cstdint> to a few files.

Thanks for reporting this!

We are working on a new release that should be out in the next few days, and will include this fix there.
