Update r-oxbow dependencies and replace deprecated APIs (#66)

* Update `r-oxbow` dependencies and replace deprecated APIs

* fix(r-oxbow): repair unverified `partition_from_index_file` impl

The implementation introduced in `5c329a6` attempted to return a
`Vec<(u64, u16)>`, which is incompatible with `extendr` and was merged
without verification. The function now correctly returns an R-compatible
List with named components (`compressed_offset`, `bin_index`).
