Update key extraction in streaming_key to be consistent with streaming_extractor_music

- Do not use equal-loudness filter
- Search for all spectral peaks (max 10000 instead of 40)
- Use the same parameters in the algorithms
streaming_key: clean code, explicitly define parameters for Key algo

- Code cleanup
- Explicitly define parameters for Key algo intstead of relying on default values
Define parameters for Key algorithms in music extractor

Explicitely define parameters to be consistent in
extractor output if default parameters for Key
will change in future.
