baracuda-kernels-types 0.0.1-alpha.68

Shared type vocabulary for the baracuda ML kernel facade: Element / IntElement / FpElement / BiasElement trait hierarchy, layout / epilogue / activation tags, MatrixRef / TensorRef views, PlanPreference, PrecisionGuarantee, and Workspace. Lifted from baracuda-cutlass so that baracuda-kernels and the per-library wrapper crates can share one vocabulary.
