v0.1.1

• New: DEBUG env var and --debug CLI arg. Useful for tracking non-critical errors.
• New EXHAUSTIVE env var and --exhaustive CLI arg for bypassing speedup shortcuts (such as the bulk S3 checks described below).
• Improvement: Faster bulk S3 checks.
• Improvement: A few DB schema changes.
• Improvement: Various DB query refinements. Some race conditions addressed and non-critical errors suppressed in normal runs (see: debug config arg to re-enable these error messages).
• Improvement: Explicitly defined Backblaze B2 storage provider, due to variations in supported commands. Currently just extends S3. B2 users should still define it as S3 until a config arg is implemented.
• Bugfix: Various other bugfixes and refinements.
