URLSearchParams usage

Do you plan on using native `URLSearchParams` API instead of `querystring` module to decode/encode query string? I see that it’s [mentioned in codebase](https://github.com/GoogleChromeLabs/native-url/blob/71705847b76a3ed020e29f8a95f4a575b51bb27e/src/parse.js#L143), but it’s not active since there is no Edge 16 support. Since this can also be polyfilled, maybe there is possibility to drop all 3rd party dependencies and go native all the way?
