Refactor camera stream settings

[uvjustin]

Proposed change

The preload_stream (keepalive) and orientation settings are used by stream but are managed/updated by camera. This requires syncing the options from camera to stream when they are updated.
This PR puts these two options into a DynamicStreamSettings class which is passed from camera into stream, avoiding keeping two copies of the options which may get out of sync.

This comparison is easier to see as an int. It happens that orientations 5, 6, 7, and 8 are rotated once so have flipped dimensions.
