feat: add obilayeredmap crate for disk-backed k-mer indexing

Introduces the `obilayeredmap` crate (v0.1.0), implementing an append-only, disk-backed k-mer index using a minimal perfect hash function (MPHF). The module features memory-mapped reads, buffered writes, custom error handling, partition metadata persistence, and comprehensive unit tests. Also adds a reverse complement benchmark for `obikseq` and updates `Cargo.lock` with the new dependencies.
