Non breaking changes

• Reworked model system to be cleaner
• Reworked throws clause to have cleaner variants and provide examples
• Added system to apply modifier to SchemaModels with annotations called SchemaProcessor
• Rebuilt validator system to not rely on reflection or the module system anymore.
• Restructured validator system to resemble the SchemaProcessor system, allowing for one hander that handles model transformation and validation.
