> This is some refactoring / tidying. Unless an output of cast has a non-determinate size (e.g. is Binary or something else), the {{CastKernel::Call}} implementation should assume that it is writing into pre-allocated memory. The corresponding memory allocation can be lifted into the {{arrow::compute::Cast}} API
