esm index.js does not work in the browser

[keroiber]

Hi

When I import index.js as esm module in the browser then the re-exported modules are not found because the extension (.js) is missing.

This should be fixed if you add the extension in the source (index.ts), e.g. export { compare } from './compare.js';

I created a fix #75 and released as v6.1.1.
