Environmental Sensing Service

Implements the BLE Environmental Sensing Service.

When subscribing to one of the characteristics, the BME680 gets triggered every 3 seconds to produce a new measurement. I chose 3 seconds as this will also the the rate at which a future BSEC MR will read data from the sensor.

Together with this https://phyphox.org/ "experiment" you can get graphs on your phone:

Looks good to me! Thanks for keeping our codebase clean.

However, I'm only a bot - so a human will still have to approve this request.
