Improve and expand sesutil(8)

- Return an error if no matching device is found when the locate command is run
- Enhance the locate command to be able to address drive bays with no disk, or where the SES controller has not made the mapping to the device name
- Added the fault command, similar to locate, but a different SES property. On some of my controllers locate blinks the activity light, others the fault light. The fault command keeps the fault light on constant.
- Improve the usage() output and use it everywhere
- Added the map command, displays all elements connected to each (or the specified) ses(4) controller
- Added the status command, returns the overall status of the ses(4) controller
