Reviewed by Eric Carlson.

We were not computing correctly the nal unit type in case array_completeness is set to 1.
We fix this by masking with 0x3F to also make sure to not be disturbed by the reserved bit after array_completness.
We copy test-bframes-hevc.mp4 to test-bframes-hevc-array-completeness.mp4 and update the array_completness bit to 1 there.
