Need to decode battery level from Manufacturer Data in ESPHome #3

Battery level is still available as a GATT characteristic, but as a beacon device, it's also in the advertisement's Manufacturer Data. Need to make that data available to Home Assistant via ESPHome.

Better yet, send battery level in the BLE advertisement using the BLEHome format that Home Assistant already understands.
