Fix the build instructions on Windows
For windows running `GYP_DEFINES='target_arch=X64'` shows an error GYP_DEFINES is
not recognized as an internal or external command.

The actual command is to set the value of GYP_DEFINES. so it should be 
`SET GYP_DEFINES='target_arch=X64'`.

Jacob Trimble a0f3f2cd3a Add cc_index to stream descriptor.
This also allows setting the language of different text streams from
the same input.  Multiple streams can use the same input stream
using different cc_index values and can each use a different language.

This also will try to pull the language from the input if not
specified.

Jacob Trimble 78be14c092 Add DVB-sub parser
Note that this only supports a single page within the DVB-sub stream.
Multiple pages will be merged together.  A follow-up will allow
selecting a specific page.

This only supports outputting using TTML or MP4+TTML; you cannot have
DVB-sub output nor can you output it in WebVTT.  Since DVB-sub
uses images, it is hard to impossible to do this with WebVTT.

This also only supports interlaced images, not progressive images
nor text.

KongQun Yang 516430bde1 [MP4] Truncate segment references in 'sidx' if necessary
The reference count in 'sidx' box is a uint16 field, which allows at
most 0xFFFF entries, i.e. at most 0xFFFF subsegments, which is roughly
18 hours for one second segments.

Do not fail packaging when it happens. Instead, generate a warning and
truncate the number of references to 0xFFFF instead.

Note that the actual number of mp4 fragments in the mp4 file can still
be more than 0xFFFF. The stream will not play to the end in DASH, but
it will play successfully in HLS.

Workarounds #862.

This changes the default MP4 output to use TTML and adds a way to
choose which one is used.  This is done with 'format=ttml+mp4' or
'format=vtt+mp4'.

This also fixes the boxes output in WebVTT in MP4.

This only supports TTML output; meaning the user can convert WebVTT

DVB-sub subtitles that would be better supported within TTML.

This only adds text-based output; a follow-up will add MP4 support.

Jacob Trimble 8e85862bda Ignore unsupported H26x streams.
This adds a new path when parsing MPEG2-TS streams to ignore unsupported
streams.  This allows extracting supported streams when some of the
streams are unsupported.  For example, you can extract audio from a
file that has unsupported video.

Jacob Trimble 1f21cc78cd Add style support for cue fragments.
Now text cues are composed of nested fragments that can be individually
styled.  This allows portions of the cue to be bold, etc.  The
WebVTT parser doesn't parse the inputs, but the original tags are
preserved in WebVTT output.  The WebVTT output will add tags if the
style elements are present in the cue object.
