Power optimization - Enable HRS3300 (heart rate sensor) sleep mode. #1756

Put the HRS3300 to sleep mode when InfiniTime is going to sleep. This change reduces the power consumption by 130µA when the heart rate sensor is disabled.

I'm not able to verify the changes, but I don't see any issues.

It works fine on my side, power usage is reduced and the HR sensor still works as expected :)
