Questions about self-contained headers.

Hi, I am wondering if jsoncons is designed to have self-contained headers. If not, when opening some headers in an IDE, it will complain about missing symbols, such as size_t in https://github.com/danielaparker/jsoncons/blob/master/include/jsoncons/ser_context.hpp. Additionally, some package managers' CI systems like Bazel may fail when enabling the parse_headers feature.

It's intended that header files include what they need, but our tests don't cover that, and up to now it hasn't been raised as an issue. We're starting to use clang-tidy to identify quality of implementation issues, so we'll see if we can apply it to that.

Thanks!
