Code in main does not compile on F38

[1div0]

I dared to upgrade to Fedora Linux 38 β. However, Exiv2 code in main branch does not compile cleanly neither w/ GNU Compiler nor w/ LLVM based Clang++.

Please see the logs.
Exiv2 GCC 13 F38.log
Exiv2 LLVM 15.0.7 F38.log

On F37 it was OK.

[RFC] Anyone experienced the same issue?

Probably need to include cstdint (or cinttypes if printf macros are needed as well) in types.hpp explicitly, most recent compilers got picky about it... Surprised our CI didn't pick this up already...

https://gcc.gnu.org/gcc-13/porting_to.html

Edit: Yep, our CI doesn't really test any more recent compiler than (outdated) Ubuntu GCC default, not good... (On Windows/MSYS2 LLVM 15 has been available for a while, but we don't test the CLANG64 environment, only UCRT64 which uses GCC 12 currently...)

@1div0 Please test and feedback if this change is sufficient.

@kmilos hvala.

Yes, the change is sufficient to fix the compilation with GCC 13 as well as Clang 15.
