Refactor `Kmer`, `SuperKmer`, and chunk reader into optimized, generic representations with compile-time length parameters and bitwise operations. Update the pipeline and scheduler to support batch processing, 1→N flat transformations, and multi-source merging. Introduce an approximate evidence mode using b-bit fingerprints and `.idx` files, alongside existing exact mode. Update CLI documentation, minimizer selection, and query output schema accordingly.
- Introduce new `obipackage` library with pipeline stages, scheduler and worker pool
- Refactor path expansion in `obiread`: replace old list_of_files with new PathIter iterator
- Add MIME type detection using `infer` crate (fastq/fasta)
- Update dependencies in Cargo.lock: add bumpalo, byteorder, cfb (with deps), fnv,
infer, js-sys/uuid/wasm-bindgen ecosystem
- Fix formatting and improve tests in SuperKmer (canonical, revcomp)
