We'll leverage on this to support a "ignore broken needles" option, necessary to properly recover damaged volumes, as described in https://github.com/seaweedfs/seaweedfs/issues/7442#issuecomment-3897784283 .

Supports two compaction methods:

* index: compacts based on the .idx file, works if deletion happened but not written to .dat files.
