Add "emergency unlock" to switchbot lock (bluetooth) integration

I love the switchbot local bluetooth integration, but a significant feature is missing. Switchbot locks have an emergency unlock feature, which is used when the lock loses its correct state. Without it, you (or your kids) risk being locked out of your own home, even if you have the keycard or pincode. I have needed to use this feature 2 times, which was a pain, since it is not yet implemented in the switchbot lock (bluetooth) integration. This meant I had to drive home from work instead of being able to perform the emergendy unlock from my Home Assistant app.
