Struct for object file source data in a add object with files call.

Set `type` and the member of `data` that matches it, for example
`OBJ_FILE_SOURCE_TYPE_FILE_CONTENT` with `data.file_content`. Leave the whole message unset for an
object without files. See
[AddObjectWithFiles](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCObjectOperations/AddObjectWithFiles/index.md) for what each type
requires.
