Include cstdint for uint16_t

[skitt]

Starting with GCC 13, cstdint is included by fewer headers and needs to be explicitly included in help.h, so that uint16_t is defined. See https://gcc.gnu.org/gcc-13/porting_to.html for details.

Thank you Skitt. You saved my eyes.

I had to add this locally too, to get it compiling/working in fedora 38
