Custom validator for unknown formats

See original GitHub issue

First of all, great module! It is working really well and saved us a lot of time.

There is an option unknownFormats to ignore custom formats. Is it possible to write your own validator and somehow inject it? Would be nice if I could use the base of this module instead of writing extra code to do same as this module does. Any other suggestions are welcome as well.

this feature is available in v4.4.0


formats: [
    name: 'my-three-digit-format',
    type: 'number',
    // validate returns true the number has 3 digits, false otherwise
    validate: v => /^\d{3}$/.test(v.toString()) 
    name: 'my-three-letter-format',
    type: 'string',
    // validate returns true the string has 3 letters, false otherwise
    validate: v => /^[A-Za-z]{3}$/.test(v)

A lot of custom formats could be validated automatically; if the pattern field was set, you could check against the enclosed regex to validate.
