Custom Error Messages

[Nick-Lucas]

Error messages need to be customisable.

• Add a definitive union literal of error types and attach them to LightTypeError throws

Provide a way to configure, ie:

• Add add .configure method to lt which returns a new lt with mappings on
• Add general mappings to the initial type creation like Zod: lt.number({ required: 'Required' })
• Add per validator messages
• Add a validation abstraction which can be passed to .pipe with just a condition callback and a message
