A new Matroska::File::save(WriteStyle style) overload is provided to
control how tags, attachments and chapters are written to the file.
- Compact: Write tags, attachments and chapters as compact as possible.
This is the default mode.
- DoNotShrink: Do not shrink elements; add void padding when content
gets smaller. Allow inserts when content gets larger.
- AvoidInsert: Like DoNotShrink but also avoid inserts for non-last
elements: replace a growing non-last element with a void of the old
size and append the new element at the end of the segment.
For very large files and/or slow (network) filesystems, using this
mode will reduce write time significantly.
