Previously, the parsing of section smart_posix_all could fail with

ValidationError (25 validation errors for ParseSection
NVMeAll.device.protocol
  Input should be 'NVMe' [type=literal_error, input_value='ATA', input_type=str]

ATAAll.ata_smart_attributes.table.0.thresh

The crash was caused by a missing threshold. This threshold was used to check the Reallocated Events (id 196). With this Werk, the crash no longer occurs. The check on Reallocated Events is omitted if the threshold is missing. You can still configure thresholds manually via the rule SMART ATA (incompatible with legacy plug-in).
