Use `import` instead of `require`

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

import { FormDataJson as FormDataJson } from "form-data-json-convert/dist/form-data-json";

After this line of code FormDataJson stays undefined. Is this supported?

Describe the solution you'd like
Support modern way of module loading.

Hi. import is not supported, as FormDataJson is not a ES6 module.

[Roland Eigelsreiter]

Support for ES6 modules now added. https://github.com/brainfoolong/form-data-json/releases/tag/2.2.0
