Message dropping issues

This library/application doesn't have a TCP reassembly system implemented, so it drops some messages. It works for many things, but expect this to be an issue specifically if you're working with ItemInfo messages. Something like [this](https://github.com/weary/reass) might be able to be used to fix this issue, but it'd require a lot of changes to the library structure.

Start by examining how the packet sniffer handles TCP data and ItemInfo messages, then compare the current behavior with the reass project linked in the issue. Determine the library-structure changes needed for TCP reassembly and verify that ItemInfo messages are no longer dropped. The issue does not name specific files or tests.
