This adds the option to configure real Wiimotes by specifying their Bluetooth addresses in
the configuration file. This allows off-brand Wiimotes to work without using the
Bluetooth Passthrough option, if you know their Bluetooth addresses beforehand.
Despite correctly setting the LAP to `0x9e8b00` in `WiimoteScannerLinux::FindWiimotes`
while scanning, which is indeed enough to make off-brand / knock-off Wiimotes respond to a
Bluetooth Inquiry, some (several? all?) bluetooth adapters seem to override and ignore
this given LAP value when performing the Inquiry, and actually use the `0x9e8b33` value as
if a null pointer have been given to `hci_inquiry`, as inspection of USB/Bluetooth packets
by Wireshark indicate. Off-brand Wiimotes don't respond to inquiries with this LAP.
If one happens to know the Bluetooth address of their Wiimote (for example, by checking
`BluetoothPassthrough.LinkKeys` after using Bluetooth Passthrough, or other means such as
directly using `libusb` to force the adapter to use the correct LAP in the Inquiry), then
it's enough to add those addresses to the vector of found Wiimotes.
Since this a niche use case and I only happen to know and have tested in Linux, this
change only affects the `WiimoteScannerLinux` backend. It's likely that it could be added
to other backends, but I'm unfamiliar with these.
If no addresses are given or this config section does not exist, behavior is completely
unchanged.
