Add check for fmt version in TensorUtils.hpp

Context

Added a version check for the fmt library to include the appropriate header file: fmt/core.h for versions older than 10.0.0 and fmt/base.h for versions 10.0.0 and later.

It solves issue #255 (closed).

Modified files

• aidge_core/include/aidge/utils/TensorUtils.hpp, added if-block to check fmt version;

Explanation

The fmt library defines FMT_VERSION as an integer in the format MmmPP (Major, Minor, Patch).
For example:

• FMT_VERSION 90100 → fmt 9.1.0
• FMT_VERSION 100200 → fmt 10.2.0
