Bangle.js 2 Cutting Edge - new heart rate algorithm

@Gordon I am working with 2 students on the algorithms for HR and steps. We would like to integrate with your work in the most efficient way so that, in case they come up with something promising, you can integrate their code easily into the firmware.

What we are going to do:

• collect raw data with reference, both step count and heart rate
  
• test out a few alternative algos and compare them in terms of accuracy / resources utilization
  
  

I am aware of these two repos that you have created:
https://github.com/gfwilliams/EspruinoHRMTestHarness
and
https://github.com/gfwilliams/step-count

We can simply push code to those 2, or, maybe more efficiently, we could merge them into one?
Some guidance would be greatly appreciated.

Thanks...
