1.0.4 - Fixing errors with regards to handling VPSs and finalized codec private to not include SEI messages.  As far as NALUs are concerned, Codec Private just stores the unique VPS, SPS, and PPS NALUs.
Fixed how we handle codec private when a previous PPS or SPS gets redefined.
Version 1.0.5

Fixed a bug with the handling of the VUI during SPS parsing.  We would output sar_width and sar_height whether or not the aspect_ratio_idc was EXTENDED_SAR.  See section E.1.1 of the HEVC spec.
