TODO:

• Pass All W3C Images with the same Selector results.
• Add more Unit Tests
• Add Benchmarks
• Implement not Implemented Functions
• Investigate AngleSharp Selector Integration (nuget or Code)
• Add more Selector Tests (Maybe port them from AngleSharp)

Fizzler Selector (Mainly slower because it needs to parse the Selector again)

I have enough Implemented for AngleSharp to run the Benchmark. here are the numbers (Maybe I need some more optimization)

There is certainly room for improvements in the AngleSharp Implementation. But I don't know if I can find there Factor 50.
