Define NOMINMAX in z_pull to use std::max

[traversaro]

Without this change, the z_pull_zenohc example fails on Visual Studio 2022 with the error:

The problem is that including windows.h defines the max preprocessor macro, that interferes with the subsequent use of std::max . By defining NOMINMAX , no max macros is defined.

With this and #134, all the zenohc based examples compile fine on Visual Studio 2022 (xref: #5), while the zenohpico one are still failing.

Closing as we no longer include windows.h (except for pico, but there NOMINMAX is defined if building for windows platform)
