Improve tests & scripts calls

Tree:
- move tests projects in a `/test` folder
- moved all scripts to be delivered in a single script folder
   - move and rename the proposed delivered GDB script to nlohmann_json.gdb
   - move and rename the proposed delivered python GDB script to nlohmann_json.py

Tests:
- add a JSON checker based on python json module
- update README.md and several scripts to new arboresence
- update CI tests accordingly

Global:
- STL are not loaded in the proposed delivered GDB script.  STL decoder loading is moved in the test part .

Also:
 - removed temporary print in STL file
 - clarify a few comments in gdb scripts
