Increase Stats.xml file size limit to 100MB

A lot of people have run into the previous ~10MB limit and increasing it
to 100MB doesn't seem to break anything.

I left a limit in place, so that excessively large Stats.xml files on a
USB profile can't be used to make a cab run out of memory. (SM uses a
multiple of the memory that is required for the file on disk.)
