DfsPackDescription: New method getTotalFileSize()

In code setting up the compact, we need to iterate over the extensions
and adding their sizes. DfsPackDescription itself is a better place
for this functionality.

Add a getTotalFileSize() method returning the accumulated size of all
extensions in the pack.
