Develop/Master Branch Merge and BicyclePower Profile and Arduino Example

[captainfips]

Hey,

I wrote a few comments on your blog a few months ago, since then much changed. I managed to get the bootloader with S340 Softdevice running and the ant_bleuart example worked finally. The problem was, that I used a newer version of the Adafruit Bootloader than 0.3.2 which made to changes to the Softdevice Size Configuration. Next I tried to change RX Mode to TX and with some additional functions in the HRM Profile that also worked. Now I moved on to creating the Power-Profile for my Bicycle PowerMeter which also went well. I created a first example with a HX711 Loadcell Amp to measure the bend of the crank and a basic Hall-Sensor to measure the current rpm. As that also worked with a self made Weighing cell (30x30mm Steel profile with 4 strain gauges) I wanted to share the Power Profile and also the example Program with you, as it belongs to your library.
This is my first time using Github so I already have to say sorry for all mistakes I made/will make.

Oh, sorry, I have been away from coding for months now. I need some time but I will review it hopefully soon. Thank you for your work!
