Simple square detection initialized

[AlexanderWangY]

Added simple script to detect a square in an image. Also includes two AI generated test images (although we will need to collect more real images when testing)

This is a good start! Great job on creating a color square detector! Just remember to install pre-commit for future PRs (pre-commit install should do it, otherwise check out the software docs). And, remember that environmental conditions will influence things like angles, lighting, occlusion, etc. which will likely test edge cases of your detector. It might be better to consider training an ML model (which Daniel can help with, when he is available/around) rather than using classical CV. Nonetheless, great start!
