KongQun Yang f49b89280c Support STYLE and REGION in WebVTT
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.

Closes #344.

KongQun Yang 51d39d96a1 Add offset to tranport streams (MPEG2-TS, HLS Packed Audio)
Configurable with --transport_stream_offset_ms.

This is needed to compensate for possible negative timestamps in
inputs, which could happen on ISO-BMFF with EditLists.

Issue #112.

Aaron Vaage e5fe2a76d2 Created Text Padder Handler To Fill Gaps
Created a media handler to come after parsers that will handle filling
in gaps between text samples. The padder takes a min duration, and if
the samples do not cover the min duration when flushed, one last empty
sample will be injected so that the samples will go up to the min duration.

Aaron Vaage b2ce6322b6 Remove Test File Index in packager_test.py
Instead of using the test file's index in a list to create the output
name, use the original filename and the descriptor.

This caused some problems with file name collisions when some tests
were using the same name. That was fixed by changing the names. This
will go away once they are transitioned to use DiffDir like the other
tests.
