GSoC'21: More error messages for FES's fesErrorMonitor

[Aloneduckling]

How would this new feature help increase access to p5.js?

Hello everyone! I am happy to tell you that I will be contributing to FES for this year's GSoC. I am mentored by @lm-n and @ghalestrilo. I am really excited to work on this project and be a part of this great community.
This enhancement is part of the first phase of my project.

FES's fesErrorMonitor catches errors which the browser shows. I will add more errors to the current list of errors, add the friendly error messages and unit tests.

Most appropriate sub-area of p5.js?

• Accessibility (Web Accessibility)
• Build tools and processes
• Color
• Core/Environment/Rendering
• Data
• DOM
• Events
• Friendly error system
• Image
• IO (Input/Output)
• Localization
• Math
• Unit Testing
• Typography
• Utilities
• WebGL
• Other (specify if possible)

I will be adding the below-mentioned errors:
