> Currently, the cuda IPC calls for `ReadRecordBatch` do not accept a dictionary memo as a parameter, building an empty memo before calling `ipc::ReadRecordBatch`. As such, adding a test which duplicates `TestCudaArrowIpc, BasicWriteRead` but calls `MakeDictionary` to create the record batch fails because the dictionaries for the original record batch are not found. The cuda IPC calls should be modified to take a dictionary memo, just like the standard IPC API.
