Display warning messages in a certain color

[vicente23]

Warning messages are not differentiated from other logging messages. We could display them in red for example.

Example of a warning message:

the qgis executable was not found

[Guts]

We've multiple options to make it:

1. switch to typer (which uses rich) to build the QDT CLI: better but it carries a lot of additional dependencies making the code more vulnerable.
2. do it roughly in "pure" argparse code.

I'm for option 2.

What do you think @vicente23 @jmkerloch?

May be I didn't understand well the initial question but it could be done by creating a custom logging.Formater ?
