Fix connecting with bleak 0.15

[bdraco]

This will work with 0.14.3 as well

There is also a performance fix in #54

I merged the performance fix from #52 into #54 and closed #52 since it would conflict

@Danielhiversen can you merge this PR, so we can test it in the latest HA beta? The SwitchBot integration is broken now because of the Bleak version.

Integration broken for me after upgrade to 2022.8.0 public release :-(

org.bluez.Device1 doesn't exist means the bluetooth adapter can't be found.

Try restarting the host and make sure bluetoothctl can see the adapter.

This isn't the place to get bluetooth support though
