Fix `default` for class object

[Tolfx]

Once compiled you need to add default to call the class, which doesn't make it that great. Would be better to find a solution on this so you can just requrie it without including .default at the end.

Same goes for https://github.com/Tolfix/simple-docker-webhook

[Tolfx]

Due to the Main.ts has export default, which means when you call import without {}, which then indicates that there is a default, which is equal to requrie("").default, perhaps we shall remove the default?

[Tolfx]

Perhaps should rewrite it to javascript and keep the types. Can't find a good solution.
