react-docgen is not compatible with react-like libraries

[Chaptykov]

There are some react-like libraries such as react-lite, preact-compat and other which use API of React for components including PropTypes. All react-docgen methods work well with these libraries. But [this module](react-docgen disables work with react-like libraries) disallows using it.

I have a preact-compat component:

import { h, Component, PropTypes } from 'preact-compat';

export default class MyComponent extends Component {
  render() {
    return <div>{this.props.children}</div>;
  }
}

MyComponent.propTypes = {
  myProp: PropTypes.func
};

Actual react-docgen returns this value for type of myProp:

{
  name: 'custom',
  raw: 'PropTypes.func'
}

If I add preact-compat to whitelist react-docgen returns expected result:

{
  type: 'func'
}

We could add a configuration option that lets you specify the module name(s) to validate against. Maybe we should add support for configuration files in the future if the configuration options keep increasing.

@Chaptykov , I realize this is an old issue, but where is the whitelist you mentioned? I see reactModules in utils/isReactModuleName, but adding preact, preact-compat, and/orpreact/compat to that array does not get the correct prop types to be created for me. I still see name: 'custom', as you described.

It turns out, the custom name in my case was not due to Preact but instead because PropTypes is not imported into each component.
