This adds more generic settings for regions and CSS styles. These are
global settings, so they go on the StreamInfo object.

This changes it from an OriginHandler to a MediaParser and moves the
handling of it to the Demuxer. This will allow more generic handling
of text by giving it the same abstractions as video/audio handling.

Opening a named pipe can block until both ends are open, and we cannot
control when the other end will be open. Ideally, we would always
open files in a thread so that Packager can be used with piped inputs
from naive applications without a potential deadlock.
This change will defer opening WebVTT files until the parser Run()
method is called from a thread. This way, WebVTT files being sent in
from a pipe will never be able to block the main thread.
Previously, files were opened on the main thread before calling the
parser constructor, passing the open file to the constructor as an
argument. I also tried doing it in the parser's InitializeInternal()
method, but that is also called from the main thread.

Note that STYLE and REGION are not supported in mp4 container due to
spec limitation as 14496-30:2014 does not specify a way to signal
styles/regions inside mp4.

We have an assert that ensures that the end time is greater than
the start time for any cue. However we never checked that cues
had a non-zero duration when parsing them.
We will throw away cues with a duration of zero (and print a
warning message) as they are not spec compliant.

Instead of having multiple char readers, one for strings and
one for files, just have one for files and use memory files
when testing.

Took the WebVTT Media Parser and created the WebVTT Parser
that will take in a file and output a stream of cues that
will later be passed to another Media Handler that takes in
cues and chunks them.
