MNT: Modularize Rocket Draw

[MateusStano]

Pull request type

• [X] Code maintenance (refactoring, formatting, tests)

Checklist

• [X] Lint (black rocketpy/ tests/) has passed locally
• [X] All tests (pytest tests -m slow --runslow) have passed locally
• [X] CHANGELOG.md has been updated (if relevant)

Current behavior

The method of _RocketPlots relating to the rocket drawing was too big and hard to change/improve/maintain

New behavior

The .draw() method has been separated into several different methods. No code relating to the plot has been changed.

Breaking change

• [X] No

Additional information

I was trying to add sensors to the drawing and it was really hard to work with the drawing, so I refactored it.

A quick note:

• There are a few lines of repeated code that could still be turned into functions. These are usually some matplotlib one-liners. I did not create a function for these because it affected readability negatively.

Also, @MateusStano can you please test the implementation in a multi-stage rocket? I think the NDRT example notebook may help you with that.

The drawing ends up identical to the way it was before. Did you find any problems there?

Nope. Sorry, I just did not have enough time to checkout your branch and run the examples.

If you have tested all the examples, I trust you. Go ahead and merge it.
