[feature] events are missing in the docs page

Describe the feature
The docs page is wonderful! But the slider events seem to be missing.

Explain it's value / reasoning
The events are a fundamental feature for a library like this.

Hi @paulovieira , thanks, yes I added the event handlers after the docs page was created.
Actually there's a fair amount missing but I never seem to find the energy to update it :(

One thing I would add, though, is that the Docs page is for the Svelte version, and really the events are not especially useful for the Svelte (reactive) use-case, as one should really be using reactive statements instead of event listeners.
