Optimize SFDT file size

The SFDT file generated by the Word Processor component is now optimized to reduce the file size. All static keys are minified, and the final JSON string is compressed. This helps reduce the SFDT file size relative to a DOCX file and provides the following benefits,

This feature comes with a public API to switch between the old and new optimized SFDT format, allowing backward compatibility.
