[iotile-sensorgraph] pod1m_vibe.sgf compiled output doesn't work

Would be useful to have the following done:
- [ ] Provide a warning that the number of nodes is too high
- [ ] Figure a way to better optimize the nodes.

The issue manifested as the following:

And it seems like the number of allowable nodes has been exceeded.

However, this snippet that was generated in the past on a POD-1M + vibration worked:
