nwztool/scsitools: cleanup and add destination changer tool
Now that we have a nice database of player index, the scsitool becomes more useful and supports a lot more players. I did some general cleanup of the code, though eventually it would be nice to really split it into a library and a CLI. The SCSI vendor command allow to read but also write most NVP nodes. Since there seems to a demand to change destination and sound pressure settings on device, I implement this feature in the tool. I do not plan to allow arbitrary NVP writes because this could easily brick the device. Changing the destination should be safe, but as usual, use at your own risks. Change-Id: Iff4e8cc3ac97b965c1df849051c5fd373756cda5
