_Tape support!_
* Major rewrite of `sas_devices`
* support other scsi devices (not only block devices), like tape drives and medium changers.
* new argument `-o, --format` to specify the fields to display
* Added `sas_st_snic_alias` to create convenient udev aliases of SAS tape drives when they are attached to an enclosure like SAS switches. The aliases are derived from the SES subenclosure nickname + bay number provided in sysfs which depends on cabling, not the drive serial number. The script is also meant to be an example and should be adapted to specific needs.
* Improved IO display in `sas_discover --counters` (to monitor SCSI commands)
