Localization

[sinclairzx81]

This PR adds error codes for each kind of validation error. These codes can be used to remap validation errors to specific locales. This functionality should allow for future i18n support in TypeBox.

The following remaps errors to French. Note that dependent properties can be obtained via the schema passed on each error.

import { ValueErrorType } from '@sinclair/typebox/error'

const errors = [...C.Errors({...})].map(error => {
  switch(error.type) {
    case ValueErrorType.ArrayMinItems: 
      return { ...error, message: `Attendu au moins ${error.schema.minItems} éléments`}
    case ValueErrorType.Boolean: 
      return { ...error, message: 'Booléen attendu' }
    case ValueErrorType.String: 
      return { ...error, message: 'Chaîne attendue' }
    case ValueErrorType.Number: 
      return { ...error, message: 'Nombre attendu' }
    // ... 
    default: 
      return error
})
