[Feature] Broadcast firmware version #397

I would like to keep my LYWSD03MMC-s up to date, it would be nice if the firmware version was broadcasted, so I could take that, and the latest release version from your GitHub repo to make a binary_sensor in my Home Assistant showing if I need to update.

i'm using the BTHome encrypted beacon, but other beacons could also benefit from such feature. I see no version related data type in the BTHome specification, but it should surely be possible to use a text data type for this.

Not welcome, as such an addition will increase battery consumption for everyone. The SW version is in the standard attributes of the BLE device.

As @pvvx says, the life of the BLE devices is directly dependant on air time. broadcasting more data than strictly necessary has a direct inpact on battery life. Simply saving 2-3 bytes means months of additional battery life out of a CR2032 battery.
