feat: remove python dependency for a build script

[seuros]

I will other PR later.

part of #132

[bvernoux]

The drawback of replacing python script by bash script is it will be working only on Linux computer (or MSYS2/MINGW64) I will really prefer a more universal way to do it by replacing those python script by C portable code built as native executable which can be executed on any computer.
To be discussed with @Baldanos

The script should work with WSL 2 (i need to test it) and it does work in macos.
We can also add Powershell if needed if the aim is to remove Python.

For cross-portability, I can provide Go, not C.

I will prefer to avoid Go (which will add even more complexity/dependencies) the aim is to have something simple and multi platform at least to build the firmware.
At start we can live with bash/shell solution (it is always better than to have Python dependency for 2 scripts) to be discussed with @Baldanos
