>+        Expose the parsing of 'cenc' init data from InitDataRegistry, so it can be used in the
>+        evaluation steps inside CDMFairPlayStreaming.
>+
>+        + Add a new method, extractPsshBoxesFromCenc() which returns an optional array of
>+          unique_ptrs to different types of ISOPSSHBoxes.
>+        + Add a peekScheme() method to ISOPSSHBox so that we can create the correct subclass
>+          of ISOPSSHBox from the above method.
>+        + Remove an extra definition of fairPlaySystemID() from CDMFairPlayStreaming.
>+        + Add 'cenc' to the list of supported types in CDMPrivateFairPlayStreaming::vaildInitDataTypes().
>+        + Add support for 'cenc' in CDMPrivateFairPlayStreaming::supportsInitData().
>+        + Format the 'cenc' init data as an encodec-JSON structure for AVContentKeySession.
