Implements missing features from [WH-1000XM3](https://gadgetbridge.org/gadgets/headphones/sony/#device__sony_wh-1000xm3):
- Sound Quality Mode (SBC Codec / HD codecs)
- Added as a switch (boolean) in UI
- Note that LDAC option can appear in Andoid Bluetooth Device settings as well as unselected. Some Android devices (eg. Samsung) will also allow changing the BT Codec in Developer Settings, but if this is not enabled, the change won't apply.
- Function of NC/AMBIENT button
- Allows using either Google Assistant or Alexa Assistant.
- This model does not support "system assistant", used for other non-Google/Alexa assistants.
