Need an esm module

[superchris]

For environments (eg importmaps) that don't do any transpilation from commonjs modules, this package is currently unusable. Any chance you could add a proper esm module to your exports? Great library, by the way.

For clarity, trying to use this in a browser testing environment, I get:

SyntaxError: The requested module './../node_modules/debounce/index.js' does not provide an export named 'debounce'

This is because only this library is only provided as a commonjs module, which browsers don't support natively.
