> For sparse-unsafe cellwise operations, we currently iterate over all cells and use binary
search to access the individual values. This is unnecessarily inefficient to should be reworked
in favor of a sequential scan with gap handling, which would also allow us to consolidate
the different code paths for sparse-safe and -unsafe operations.
