Add option to change Sampling- and Bitrate

The default sound quality is really bad (8kHz sampling rate).

Please add an option to let us change the EncodingBitRate and SamplingRate.

Android Example:
```
this.recorder.setAudioEncodingBitRate(192000);
this.recorder.setAudioSamplingRate(44100);
```

Locate the Android media recorder entry point and trace how EncodingBitRate and SamplingRate are currently handled; start with the existing Android example in the issue. Confirm how options are exposed to callers, then verify that recording uses both configured values instead of the defaults.
