utils.hpp missing cstdint

[RPGillespie6]

I get the following compile error on g++ 13.2:

../ext/gzip/utils.hpp:15:36: error: ‘uint8_t’ does not name a type
   15 |                        static_cast<uint8_t>(data[0]) == 0x78 &&
../ext/gzip/utils.hpp:2:1: note: ‘uint8_t’ is defined in header ‘<cstdint>’; did you forget to ‘#include <cstdint>’?
    1 | #include <cstdlib>
  +++ |+#include <cstdint>

Adding #include <cstdint> to utils.hpp fixes the issue
