Support typescript utility types

[igorovic]

I seems that typescript utility types are not supported.

import jwt from 'express-jwt';
import jwks from 'jwks-rsa';

export default interface ConfigOptions extends Omit<jwt.Options, 'secret'>, jwks.ClientOptions {
    secret?: Pick<jwt.Options, 'secret'>,
    issuer: any,
    audience: any
}

Utility types

• Omit
• Pick

The generated schema looks like this.

export const ConfigOptionsSchema = {
  "$schema": "http://json-schema.org/draft-07/schema#",
  "additionalProperties": false,
  "patternProperties": {
    "^[0-9]+$": {
    }
  },
  "type": "object"
};

Same result with --format full

Am I doing something wrong?
