feat: add obisys crate for standardized CLI progress reporting

This commit introduces the `obisys` crate, which wraps `indicatif` to provide reusable `spinner` and `progress_bar` utilities with consistent styling and tick intervals. It refactors progress reporting across `obikindex`, `obikpartitionner`, and `obikmer` to use these shared functions, eliminating inline UI configuration and ensuring uniform terminal feedback.
