v0.15.0

This is the first release available with a pre-built binary image you can flash to the ESP32.
Once loaded, you'll need to connect to the ESP's access point and upload a configuration file (config.json) and reset.

You can flash the full image using the following command:

esptool.py -p <Serial / COM device> -b 115200 --chip esp32 write_flash 0 build/ble2mqtt-full.bin
