- Add ahash dependency to workspace, filemeta, and utils crates
- Change FileInfo.metadata to AHashMap<String, String>
- Change ObjectPartInfo.checksums to Option<AHashMap<String, String>>
- Change MetaObjectV1.meta to AHashMap<String, String>
- Change MetaObjectV1Part.checksums to Option<AHashMap<String, String>>
- Change UniquePartChecksums to use AHashMap
- Make metadata_compat functions generic over BuildHasher
- Make get_internal_replication_state generic over BuildHasher
This optimization replaces the standard library's SipHash with ahash,
which provides 2-3x faster hashing for typical key types.
