The `ensure_correct_sparsity` function is intended to provide a means of aligning the in-core index with the sparsity required by the repository settings and other properties of the index. The function first checks whether a sparse index is allowed (per repository & sparse checkout pattern settings). If the sparse index may be used, the index is converted to sparse; otherwise, it is explicitly expanded with `ensure_full_index`.
