What is the current behavior?

It's quite hard to compare different aspects of a flight when you have more than 1 stage rocket.
Also, a lot of code lines at Flight.py are dedicated exclusively

What is the new behavior?

• Print and Plot functions were mode from Flight.py to a submodule called rocketpy.plots.flight_plots
• The old Print ad Plot functions of Flight.py now are calling the functions available at the new file
• Now there's a for loop inside each plot, allowing you to generate the outputs for n flight objects
• Also, several compare functions were added, allowing the user to se different flights in a specific chart. Let's say, if you have 10 flight objects, you can plot all the flight.speed at once, in a single figure.

Does this introduce a breaking change?

• Yes
• No

Other information

Quite large pull request... But I swear, once you get the idea of one plot, you'll definetely understand the other. The trick part is only about how to initialize the flight_plots class, I confess that I'm not so pround of the difficult to initialize the class, but it's working properly anyway.

Many thanks to github copilot, this little guys has worked like hell past couple days.

Tests are working offline but not on github, I have no clue of what is going on

This PR will be desconsidered. @MateusStano is about to create another PR based on beta\v1.0.0 where we will be refactoring all rocketpy plots instead of only those from flight class. I'll link that PR here as soon as he opens it.

The branch will be preserved so we can use the code in the future if needed.
