Subject: [PATCH] health: add hrm info to readme

reference:

> The health app on the Bangle only stores data every 10 minutes. The '3 minute' option is for the heart rate - it'll take 3 HRM samples every 10 minute slot and use the best/average value of HRM readings - but it only stores one reading per 10 minutes.
