Description
There are some matrix types for which we can directly compute the optimal coloring, like (block-)banded matrices.
ArrayInterface.jl does this already but only for column coloring. We could reuse some of that code (if the license is right) and generalize it to other colorings (row, symmetric, bidirectional).

Research direction
Review the related issue #64 and ArrayInterface.jl's existing column-coloring implementation first, including whether its license permits reuse. Then determine how banded and block-banded matrices should support column, row, symmetric, and bidirectional colorings, with optimal coloring results for each supported type.
