When we started fetching partial HLS segments to find the start time,
we were no longer able to start playback for content with a moof box
larger than the partial segment. This is because we parsed the boxes
hierarchically, which required the entire payload.
Now, we can selectively instruct the parser to tolerate a partial box
if the part we have includes the child box we are looking for.
This fixes playback of several pieces of HLS content in our demo app.

This speeds up HLS stream startup significantly for servers that
permit this kind of request, and falls back to full segments for
servers that do not.

This converts from using ArrayBuffer in the text parsers to using
Uint8Array. This avoids doing extra buffer copies when using
ArrayBuffer.slice().

When defining a box, the box would be defined as a four
byte integer. Now there is a "fromString" function that
can be used to convert a four character assci string to
a four byte integer.

Before the segment start time and end time were used to determine
the start and end time for all subtitles that appeared in the MDAT
box. The time values for each subtitle is specified in the TRUN box.
Now the time values are extracted from the TRUN box and mapped to
the correct subtitle in the MDAT box.

Before parsing Mp4Boxes was done using the "findBox" method. This
was limted to only looking at one level of the structure and
required a large amount of code to dig deeper into the structure.
This change creates a generalized Mp4 Box parser that should
simplify parsing Mp4Boxes. This will help work on #699.

Rather than having it in the DashParser as a network response filter,
we should have it in StreamingEngine. This will give it access to the
segment times so we can calculate the presentation times for the event.
Otherwise, there is no way to know when the event should actually occur
since the app can't know which segment is being downloaded or which it
came from.
This also adds startTime and endTime fields to the event so the app
doesn't have to calculate them. For reverse compatibility, the old
fields will still exist.
