The documentation suggests to use CameraConfiguration::operator[] to
access the StreamConfiguration it contains, but as CameraConfiguration
instances are generated by the Camera class and are returned wrapped in
a unique_ptr<>, the usage of operator[] would require an awkward syntax such
as (*config)[i].
Better to suggest the usage of the CameraConfiguration::at() function
instead to access the StreamConfigurations.
