ISO/IEC 14496-15 says about the `HEVCDecoderConfigurationRecord`:
> **array_completeness** when equal to 1 indicates that all NAL units of
> the given type are in the following array and none are in the stream;
> when equal to 0 indicates that additional NAL units of the indicated type
> may be in the stream; the default and permitted values are constrained
> by the sample entry name;
This PR sets `array_completeness` to 0 if parameter NAL units may appear
in the stream when they are not stripped by
`--strip_parameter_set_nalus`.
This should increase player-compatibiltity for streams with mid-stream
SAR changes.
