export also as ESM module

[mojoaxel]

We get the following waning in an Angular project using keychartm (for vis-timeline):

WARNING in node_modules/vis-timeline/esnext/esm/vis-timeline-graph2d.js depends on 'keycharm'.
CommonJS or AMD dependencies can cause optimization bailouts.
For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies

It would be helpfull to also export a ESM module.
I'll try to look into this issue within the next weeks, but if somebody wants to help, please feel free to do so ;-)

@AlexDM0 Maybe you can label this issue with Hacktoberfest!?
(see https://hacktoberfest.digitalocean.com/#maintainers)

[AlexDM0]

@mojoaxel Sure, it's labeled. Let me know what you find!

[mojoaxel]

@AlexDM0 Sorry to bother you again but to be part of hacktoberfest the project needs a "topic" hacktoberfest to the project. ;-)

Maintainers of the repository can add the "hacktoberfest" topic to their repository if they wish to participate.
Alternatively, an individual PR can be opted-in with a maintainer adding the "hacktoberfest-accepted" label to the PR.

@mojoaxel I've added you as a contributor. I havent looked too much into hacktoberfest, so if you think this would be a fun candidate, I'll leave it up to you to add it :)

I've added you as a contributor.

Thanks, but with the current rights I cannot add topics or labels 😉 but that's ok...

[AlexDM0]

I see, I added the topic now. I didn't know those existed to be honest :)
