* fix: Use `bitRate` multiplier instead of setting it to an absolute value

* Pass override

* Format

* Rename

* feat: Also implement Android

* fix: Log Mbps properly

* fix: Up-/Down-scale bit-rate if different options

* fix: Parse in Manager

* Update RecordingSession+getRecommendedBitRate.kt
