   `ColumnCloseResult` is currently defined as
   
   ```
   type ColumnCloseResult = (
       u64,
       u64,
       ColumnChunkMetaData,
       Option<ColumnIndex>,
       Option<OffsetIndex>,
   );
   ```
   
   Not only is this type alias not public, but it isn't immediately apparent what fields are which.
   
   **Describe the solution you'd like**
   <!--
   A clear and concise description of what you want to happen.
   -->
   
   ```
   /// Metadata returned by [`GenericColumnWriter::close`]
   #[derive(Debug, Clone)]
   pub struct ColumnCloseResult {
       /// The total number of bytes written
       pub bytes_written: u64,
       /// The total number of rows written
       pub rows_written: u64,
       /// Metadata for this column chunk
       pub metadata: ColumnChunkMetaData,
       /// Optional column index, for filtering
       pub column_index: Option<ColumnIndex>,
       /// Optional offset index, identifying page locations
       pub offset_index: Option<OffsetIndex>,
   }
   ```
