Snapshot verify can now accept a list of one or more snapshot IDs (manifest IDs) to be used as the subject(s) of the snapshot verify operation. Added a unit test that ensures only the requested snapshots are verified when their IDs are provided. Now in addition to the existing --source, --file-id, and --directory-id flags, which work the same, the user can provide snapshot IDs as args: kopia snapshot verify <snapID> <snapID> <snapID>
