examples have errant printf parameter usage

[diablodale]

I have so far found 4 instances of improper printf usage in the examples.
Throughout the depthai codebase, there is a often used 32-bit viewpoint. They are exposed when compiling for 64-bit and I can see this in float/int issues and now in printf issues.
I can see you specifically enabled such detection in clang in flags.cmake.
I have found it in MSVC.

Setup

• depthai-core c1b697a
• MSVS 2019 Community v16.11.6
• build= Debug and 64-bit

Repro

1. cmake config, and build (including examples)
