> The `TryClone` bound currently needed in `ParquetWriter` makes it awkward to write parquet to memory, forcing either a `Rc` + `RefCell` wrapper or to write to a `File` first.
> By explictly threading lifetimes around the underlying writer can be passed mutably through all parts of the writer, allowing `&mut Vec<u8>` or any other implementors of the basic io traits to be used directly.
