As I mentioned in this issue here, I'd like to be able to specify an X-TIMESTAMP-MAP based on some external factors in my application which uses astisub. However, as part of this, I think that the WebVTT reader automatically applying the time offset defined therein will cause duplicate applications of the time offset in the case where a WebVTT with an X-TIMESTAMP-MAP is read, manipulated, then also written back out.

So this PR adds a struct for storing the parsed X-TIMESTAMP-MAP data on the Subtitles' Metadata field, that way it can be manually applied to the subtitles if necessary, or left as is and written back to WebVTT files so that some upstream client can apply the time correction. Likewise, this also allows manually configuring a X-TIMESTAMP-MAP to be written to a WebVTT file when it previously did not exist there, the use-case I originally needed to solve for.
