* Replaced smartmontools with smartmontool-svn
* Adds JSON exporting which makes parsing the data easier
* Using nvme-cli for NVMe drives instead of smartctl
* NVMe support in smartctl is still experimental and inconsistent
* New "Health OK" detection
* This is used to determine if a disk is okay to be tested
* e.g. an IDE disk w/out any SMART data now requires explicit overriding
* NVMe disks are set using the "critical_warning" attribute
* SMART disks are set using the "overall-health" attribute
