Extended Click Event Handlers

[stephencorwin]

Following the existing examples of the onClick implementation, I extended the event handlers to support both onDoubleClick and onContextMenu.

The main reason for this PR is that I need to support "right-clicking" in my game. I was surprised to find that support for it didn't exist yet in R3F. The corresponding handler in React is onContextMenu. I looked through the discussions and didn't see any conversations about it yet, however I did see one about onDoubleClick. I figured I would add support for that event as well since I'll probably need it too 😉

Please let me know if there is anything I can do to get this merged. Thanks again for this awesome library @drcmda!

@stephencorwin some users have reported that click isnt working on mobile, could you look into this? it probably will affect contextmenu and dlbclick as well ...

@drcmda I can take a look into it. 👍
My inclination is that the event my be named differently by the browser and/or that the escape hatches for "click" in handlePointer is not handling tap events correctly.

@drcmda Update: Click + Click-and-hold (ContextMenu) on Mobile seem to work. onClick attached to a mesh works ONLY if there are no click handlers on the <Canvas />. Otherwise it looks like the Canvas eats up that event. onDoubleClick doesn't seem to be supported on mobile. Hopefully that helps.
