This patch includes:
* Documentation update.
* Code simplification and correctness; the value overloads based on the
size of the hrm counter has been removed in favor of runtime check which
is more correct.
* The control point characteristic has been removed since HeartRate value
byte does not support the accumulated energy expanded.
In the process, the path has been shortened and the unecessary ble
directory between FEATURE_BLE and the actual implementation has been
removed.
