In #123 we added the support for cuSPARSELt v0.0.1, which was the version that CuPy tested against (cupy/cupy#4883). However, cuSPARSELt v0.1.0 just came out, and once https://github.com/conda-forge/cusparselt-feedstock/pull/9 is finalized perhaps we could consider rebuild CuPy to support it. (A rebuild is needed because currently we pin at the exact version of cuSPARSELt.)

The question (https://github.com/conda-forge/cupy-feedstock/issues/111#issuecomment-824244544) needs to be addressed first: Would v0.1.0 be compatible with the support added to CuPy?
