Fix camera lookup to check for physicalId (#792)

* Fix camera lookup to check physicalId

Check `physicalId` in addition to `deviceId` when looking up the camera configuration. This resolves issues on devices where the logical and physical camera IDs may differ.

* Add changeset

* Add physicalId to camera selector
