[Feature Request] Use of native iOS camera interfacing for full features

Is it possible for Riot on iOS devices to use the native camera interface instead of the basic one it has now? There's a whole lot of features missing with the current camera method.

The issue does not identify a file, test, or camera entry point. Begin by locating Riot’s current iOS camera implementation and defining which native camera features are required; done means the scope and expected behavior are agreed.
