- Moved the netflow library out of the src directory
- The UDP listener was restructured so that multiple threads can receive
packets and push them into a queue. The main thread then pulls the
packets off the queue one at a time and processes them. This means
that the collector will never drop a packet because it was blocked on
processing the previous one.
- Adds a property to the ExportPacket class to expose if any new
templates are contained in it.
- The collector will now only retry parsing past packets when a new
template is found. Also refactored the retry logic a bit to remove
duplicate code (retrying just pushes the packets back into the main
queue to be processed again like all the other packets).
- The collector no longer continually reads and writes to/from the disk.
It just caches the data in memory until it exits instead.
