Move to ES Modules

[reesericci]

Adds support for use as an ESM module with the following syntax:

import Filter from 'badwords'

[web-mech]

I think it's fine to support ESM here without needing to support both ESM + CJS. But this will need to be a part of a major release. We should also update the dependencies being required here.

Any update on this?

[reesericci]

As far as I know, this branch is working and I'm not sure what the timeline is on being merged. I'll go through and make the dependencies use ESM import though to resolve the changes requested by @web-mech .

[reesericci]

Just moved everything over to ESM in this PR!

[TamimiGitHub]

Fantastic, thanks for that @reesericci! I'll keep an eye out on the next release

[web-mech]

Thanks @reesericci , will see if we can merge this in soon
