[FEAT]: Extract events

[jjagielka]

Description

Current extractEvents function catches all on:event exported from the component.

However, components often define emitted events via svelte function:

<script>
  import createEventDispatcher from 'svelte';

  const dispatch = createEventDispatcher();

  dispatch("eventName", customData);
</script>

Those needs to be caught as well.
