Add support for PropTypes.elementType in the element prop

[guillermodlpa]

Is your feature request related to a problem? Please describe.

I'm using Obfuscate with Chakra UI, a component library for React, that provides a Link component that is already on-brand and with useful utilities. Obfuscate works fine passing a React element type in the element prop, but the prop types validation expects only a string, not a React element type.

Example usage:

import { Link } from '@chakra-ui/react';
import Obfuscate from 'react-obfuscate';

function MyComponent() {
  return (
    <Obfuscate email="example@example.com" element={Link} />
  );
}

This works, but it produces the following console error log:

Warning: Failed prop type: Invalid prop `element` of type `object` supplied to `Obfuscate`, expected `string`.

Describe the solution you'd like

Probably just update the following line:

// obfuscate.js line 129
- element: T.string,
- element: T. oneOfType([T.string, T.elementType]),

Line: https://github.com/coston/react-obfuscate/blob/master/src/obfuscate.js#L129

and add a unit test for this scenario.

Describe alternatives you've considered

I'd be happy to make this contribution, just want to open the issue first in case the element prop only accepts strings by design.

Thanks

EDIT: I realized later that there's a problem with the output, and the resulting a tag when setting element={Link} doesn't have an href 😅. That is because of the check here that is specifically doing Component === 'a'. Is there a reason for that, or could it be removed to pass those props in all cases?
