Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.
Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.
The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.
Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.

bear-320x240.webm - WebM encode of bear.1280x720.mp4 resized to 320x240.
bear-320x240-vp9-opus.webm - Same as above, but with vp9 and opus codec.
no_streams.webm - Header, Info, & Tracks element from bear-320x240.webm slightly corrupted so it looks
like there are no tracks.
nonzero-start-time.webm - Has the same headers as bear-320x240.webm but the first cluster of this file
is the second cluster of bear-320x240.webm. This creates the situation where
the media data doesn't start at time 0.
bear-320x240-live.webm - bear-320x240.webm remuxed w/o a duration and using clusters with unknown sizes.

// ISO-BMFF streams.
bear-1280x720.mp4 - AVC + AAC encode, mulitplexed into an ISOBMFF container.
bear-640x360.mp4 - Same as above, but in a different resolution.
bear-640x360-hevc.mp4 - Same content, but encoded with HEVC.
bear-320x180.mp4 - Same as above, but in a different resolution.
bear-640x360-trailing-moov.mp4 - Same content, but with moov box in the end.
bear-640x360-av_frag.mp4 - Same content, but in fragmented mp4.

bear-640x360-non_square_pixel-without_pasp.mp4 - A non-square pixel version of the video track of bear-640x360.mp4 without PixelAspectRatio box.
// Encrypted Files.
bear-640x360-v_frag-cenc-aux.mp4 - A fragmented MP4 version of the video track of bear-640x360.mp4
encrypted (ISO CENC) using key ID [1] and key [2] and with sample
encryption auxiliary information in the beginning of mdat box.
bear-640x360-v_frag-cenc-senc.mp4 - Same as above, but with sample encryption information stored in
