PdfProcessing: Implement PdfFileAppender class allowing to modify single PDF file by appending bytes at the end of the file

This would ensure preserving the existing PDF file pages and document properties untouched and additionally would allow making a few modifications to the file. By appending bytes to existing PDF file one may achieve:

 - Modifying specific pages content and properties.
 - Adding new pages to pages collection.
 - Modify some document properties (such as Bookmarks).
 - Edit interactive forms field values.
 - Add digital signatures to existing documents.

This feature would allow programmatically completed PDF form documents to avoid the output file size bloat that currently occurs. In my test cases, simply importing a sample document and then exporting it, with no changes, results in roughly a 3-4 X increase in output size, from ~350 KB to ~1.1 MB.
