v.2.0.0 for 2024 submissions

• Provided guidance to generate coverage information.
• Expanded features list and provided a visual test case distribution.
• Included useful links to Godbolt, simulator, ISA, ABI, Assembler reference.
• Directly linked to ANSI C parser and lexer.
• Added a "Getting started" guide and incorporated last year's feedback from Ed.
• Changed the 10% of the grade (previously only for time management) to also account for code design to reward thoughtful planning.
• Improved the skeleton compiler to be more advanced by integrating lexer and parser to hopefully jump-start progress and avoid unnecessary debugging.
• Covered assembler directives in more details by showcasing the meaning behind an example assembly program, because that topic had always caused confusion in the past years.
• Added an improved testing script written in Python.
