> Often removeEmpty is used to guard against special cases with entirely empty
> rows or columns. In case of no removed rows or columns the full copy into the
> output is unnecessarily inefficient. This task aims to modify removeEmpty
> rows/cols for both dense and sparse matrices to leverage a shallow copy if
> determined output dimensions match the input dimensions.
