fix a bug where missing STREAMINFO fields (min/max framesize, total samples, MD5 sum) and seek point offsets were not getting rewritten back to Ogg FLAC file (SF#1338969 https://sourceforge.net/tracker/index.php?func=detail&aid=1338969&group_id=13478&atid=113478)

The following are major known bugs in the current (1.1.3) release:
<ul>
<li>
(none)
When encoding to Ogg FLAC, if there are too many seek points (&gt;240), the seek table will not have the offsets written back properly after encoding.
</li>
</ul>
The following are major known bugs in the 1.1.0 release:
