Introduces a new `obikselect` module to handle k-mer selection and column aggregation. Adds a `select` CLI command in `obikmer2` that supports group predicates, aggregate operators, and output column filtering. Implements operator parsing with case-insensitive matching and default rules, along with a centralized module for resolving group specifications from metadata or genome filters. Updates dependencies to include the new crate and its prerequisites.
