The implementation

Currently, the xssf.streaming can be used only to create new xlsx documents, not to open and change existing xlsx documents.

It would be nice to be able to open an existing xlsx document (as a template) and add to it (rows to existing sheets, new sheets, etc) while taking advantage of the very low memory reqs for xssf.streaming.

The attached patch adds this functionality.
