Fix build for Ubuntu 24.04

[ruffsl]

When building from source for ROS 2 Jazzy via Ubuntu 24.04, one may encounter undefined uint8_t types:

Starting >>> sick_safetyscanners_base
--- stderr: sick_safetyscanners_base

The difference in behavior between GCC 11.4.0 and GCC 13.2.0 may likely be due to changes in the C++ standard version used by default by the compiler, or changes in the implementation of the standard library. I think in C++11 and onwards, uint8_t is defined in the header. However, some older versions of GCC, or some configurations, might have allowed uint8_t to be used without explicitly including , possibly because another standard library header included indirectly?

In GCC 13.2.0, it seems that this is no longer the case, and we need to explicitly include to use uint8_t. But perhaps this is more in line with the C++ standard, which requires explicit inclusion of the headers defining the types used.

Oh, possible duplicate of this, although I didn't seem to need to add #include <string> for building locally.

• Fix header includes for <cstdint> and <string> #25

Yes - same base cause - Noble updates :). We are iwyu so the was probably a cppcheck info warning (haven't double checked).

Not sure any owners are monitoring this repo currently - my PR was from Feb, might need to go through the company rep process for a prod etc.

@puck-fzi , please see this fix to help with your release into Jazzy:

• New ROS2 release ? sick_safetyscanners2#43

Closing since #25 was merged
