transcode bitrate configurable for subsonic server

[amazingfate]

Is your feature request related to a problem? Please describe.
I'm connecting to a gonic server (go implemented subsonic server). The flac is always transcoded to 128 kbps mp3. I can see the server log:
2022/08/25 03:10:14 response 200 for /rest/stream.view?id=tr-792&u=admin&s=xxxxxxxxxxxxxxxxxxxo&t=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&v=1.13.0&c=sonixd
I also ultrasonic as client on android, which has a setting of MaxBitRate. Here is the log when ultrosunic is playing music:
2022/08/24 11:02:31 response 200 for /rest/stream.view?id=tr-792&maxBitRate=320&u=admin&c=Ultrasonic&f=json&v=1.15.0&t=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&s=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
It seems that there is a parameter maxBitRate in api stream according to the subsonic api document
Describe the solution you'd like
We can configure the bitrate to transcode just like ultrasonic.
