Current behavior

We know that sometimes it is hard to check if we have correctly defined the rocket before simulating it.
Also, sometimes we just need to ensure that our rocket looks good on RocketPy.

New behavior

Just added a method to draw the entire rocket. You can already try the Rocket.draw() method.

Here the first example:

Breaking change

• Yes
• No

Additional information

Some comments on the reviewing process:

• We still need to test the code under different scenarios.
• I currently don't know if by any chance we could create an unit test that will check if the plot was created correct. Instead, we keep just checking if the method is called without raising any errors.
• Waiting the review to elaborate some more specific tests, accepting suggestions meanwhile.

Have you ever wondered if there is something better than "spectacular"?
Well, @MateusStano have found it.

Great Work!! I've been able to debug some rockets thanks to the new implementations.

The only flaw I could find so far is the position of the legend, this is a problem with matplotlib in general.
Avoiding legend overlap is sort of annoying task.
