Screenshot as instant perspective #24

usable also for rM sleep screen

ideally linking back to actual content timestamp

see https://aframe.io/docs/1.3.0/components/screenshot.html#methods

Working on headset as a jxr command but saves locally. Still have to be sent somewhere. Consider rewriting to avoid saving as file but rather sending remotely.

See also https://dougengelbart.org/content/view/218/ on the broader context. Important to keep in mind how to link back to this specific view, pose and timeframe.

Consider also a non flattened screenshot, namely a 3D screenshot and including the semantic content within view. That also means being able to repeat the same coherent interaction, namely to pick then "pull across", cf #56 , the content to one's own space.

This could be done by exporting part (cf THREE.Frustum() and .intersectsObject() as suggested in #26) of the scene, within a viewport, to a glTF.

See also https://threejs.org/docs/#examples/en/exporters/GLTFExporter and relying on the Inspector https://github.com/aframevr/aframe-inspector/blob/master/src/components/scenegraph/Toolbar.js#L47

As shown in https://twitter.com/utopiah/status/1614634307804438528 but should also add the context, e.g timestamp, pose, etc.
