feature request: native ES module support

[JounQin]

I don't know have you considered rewriting this package with native ES module or TypeScript instead?

Or we can bundle it to ES module with rollup.

I'd glad to raise a PR if you agree.

It would be appreciated for any Angular10 project.

Would also love this feature - please consider!

Since 3 years have passed without any action - have a look at croner, which is compatible with ESM and can replace cron-parser in many scenarios
