Basic sanity testing for 2D and 3D sketches.

[tushar5526]

To help the maintainers review new PRs easily, I have put together some p5 sketches from the documentation covering various APIs of the p5py package.

It runs all the sketches for 2 seconds headlessly and checks for errors and prevents PRs from being merged that would break the functionality of the library.

#308 broke the 3D rendering pipeline, so I have reverted the changes. Maybe @janbehrens @ziyaointl could look into it.

Thank you! This is excellent work and I'm sure all p5py contributors would appreciate this addition to the project. I'll take a closer look at the renormalization problem in the 3D pipeline today and post an update :)

Just to mention, we are setting up p5 multiple times for each of our actions. Instead, we can save and upload it as an artefact and save some processing power. I will cover this in a different PR soon.

That's a good idea! Thanks for working on it!

Also, I found the reason of why the 3D pipeline was breaking - #308 did not convert the return value to an np.array. I'll open another PR that fixes the issue after this one is merged :)

Thank you @tushar5526 for your timely responses! I'll go ahead and merge this PR :)
