Support for BDV-N9200W

Hello. I noticed on the homepage that python-songpal supports BDV-N9200W, but I encountered the following issue when I attempted to control it:

songpal --endpoint http://192.168.1.187:10000/sony -dd power

Unable to get supported methods: Got an error for getSupportedApiInfo: NoSuchMethod (12): getSupportedApiInfo

I found this issue and some pr related to this, but I didn't see specific instructions on what I should do. https://github.com/rytilahti/python-songpal/issues/29 And there is a branch feat/allow_local_devinfo. Should I use it for my device?

I'm not sure when it got added to the list of supported devices, but apparently it shouldn't be there. That PR got never finished, so there's unfortunately no easy way to control that device.
