4a-hal-unicens: add Fiberdyne Master Volumeflounder_6.0.3flounder_6.0.2flounder/6.0.3flounder/6.0.26.0.36.0.2

Bug-AGL: SPEC-1758

As preparation before introducing UNICENS 4a plugin:
- Init volume library at first
- Add fiberdyne master volume
- Introduce commands sent by control messages
- Removes outdated controls
- Known issue: turn ALSA volume above "93" to hear some sound
