A partial parser for WebVTT segments. Interprets enough of the WebVTT stream
to be able to assemble a single stand-alone subtitle file, suitably adjusting
timestamps on the way, while everything else is passed through unmodified.
Regular expressions based on the W3C WebVTT specification
. The X-TIMESTAMP-MAP extension is described
in RFC 8216 §3.5 .

An object that maintains the current parsing position and allows
conveniently advancing it as syntax elements are successfully parsed.

A child parser state, which advances through the same data as
its parent, but has an independent position. This is useful when
advancing through syntax elements we might later want to backtrack
from.
