This lets them be a base class for nodes that must be on chip, like DVS nodes.
Works in emulator and on-chip, but does not use the on-chip structures required for live DVS.
This allocates 85 cores like the live DVS, so that file-based and live DVS can be as similar as possible.

This supports input from a live DVS camera. It is an update of #235, and is based of #306.
I've tested the
use_coresflag, which uses Loihi cores to route input the same as with a live DVS, but still reads from a file. The output is qualitatively similar to what we would expect, however the spike rates are significantly different, suggesting that there's some sort of scaling issue there.The live DVS portion has not been tested since the rebase. At the very least, some imports need to be updated for the newer NxSDKs.
Also note that this does not include any of the additional commits in the
dvs087-tcsbranch. I don't think any of these additional commits are necessary to get live DVS working, but they may be useful.
