Use the new flows system rather than Heimdall to display the circuits flows tab. Not complete yet - the backend is all there still. Also needs some tweaking on the hyperfocus for packet capture mode.

Revert from a dashmap to a regular mutex for the flow container. Performance improved, and flow removal is less troublesome.

Stage 1 of the revamp. Instead of modifying traverseNetwork directly, builds a layer per CPU in the network and then uses the previous code.

On flat networks, read calculated LTS (or not) weights and apply them to the binpacking circuit weights if found. This makes binpacking more dynamic for flat networks, taking into account usual usage patterns.

Compromise on 10ms sampling time for rate estimation. Giving pretty accurate results on my tests, and not hitting the CPU too hard.

Reduce the flow rate estimation frequency from 1 second to 1 ms.
...
This reduces round-error issues and is generally more accurate -
at the expense of slightly higher CPU usage and a "more bouncy"
rate - that is, for a widely variable flow such as Netflix it
jumps around a lot more. I remain unconvinced that 1ms is the
right number - will continue to test.
Thanks again to Simon Sundberg for this suggestion.

* Remove most code duplication by tracking rate_index and its reciprocal.

* Significantly nicer comments.
* I used a ternary operator. Please shoot me.
