feat: add click events to scene

[toddeTV]

• click on a model will trigger a function
• cache the clicked model so that it has a "selected" state for later operations
• deselecting models should also be possible by clicking on another model or even the background to deselect everything
• type the event https://docs.tresjs.org/api/events

Got a bit of progress. It seems to be a ThreeEvent<DomEvent>. From your properties only the ALT_MASK is missing.

In the browser console Event.ALT_MASK works but apparently this is missing from the typescript types...

See #27

Thanks a lot 😊
For now, I will stick to the typing you suggested. It's not ideal as we do not know what else might be missing in the typing, but it's good enough for now.

import { type DomEvent, type ThreeEvent } from '@tresjs/core'
function onNodeClick(event: ThreeEvent<DomEvent>&Event){ ... }

With the TresJS core v4, the Outline Post-Processing is not working.
All we currently can do is going back to TresJS core v3.9.0 and use the Outline effect with this old version.
So this task will now only focus on the logic for clicking and what then will happen - but not the oufline effect when selected and also not the outline effect on hover, therefore issue #32 was created.

I already created part of the needed code for the highlighting. Please do not delete it and let it commented out in the code.
