Description

Enable colored output with Spyder

This PR addresses two issues:

• colorama needs to be initialized with the option strip=False in Spyder
• In the spyder environment the method is_terminal returns False, where it should return True. This is solved by creating a new method detect_spyder_environment

I can't accept a fudge for a specific IDE. Colorama is a headache for Rich as it makes global changes, whereas Rich can have different settings per-Console instance.

I'd suggest setting force_terminal on the constructor if Spyder is reporting it is not a real terminal. You can also reinit colorama after importing rich to fix that issue.
