Make RSSI non optional #312

I think every Advertisement packet comes with an RSSI (Android, macOS). We should mark the rssi property as always present in BluetoothAdvertisingEvent

Windows? If so, great!

In 8.1 there are no advertisements because there is no support for scanning. The windows 10 APIs do include RSSI: https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.bluetooth.advertisement.bluetoothleadvertisementreceivedeventargs.aspx

Shall we include this in our Windows implementation status notes? 

 * [Windows](https://crbug.com/507419): Requires Windows 8.1.
   * To discover devices the user hasn't yet manually paired, requires Windows 10.
+  * The Scanning API will require Windows 10.

Btw, if RSSI is not available on some platform, there is a magic value for indicating this specified in the Core Bluetooth spec, RSSI +127.

The magic value can be used both in the case when reading the RSSI of a scan result, as well as the case for reading a connection's RSSI.

Relevant parts of the spec:
