blocksToMarkdown() drops sublist items in a column

[andrew-polk]

Steps:

• In Notion, create two columns.
• In the first column, create a numbered list.
• In the numbered list, create a sublist item.
  

The column_list block will look like

{
  "object": "block",
  "id": "5fcf1c58-3ddf-495c-a2c4-22376bcab1fd",
...
  "has_children": true,
  "archived": false,
  "type": "column_list",
  "column_list": {}
}

but the result of blocksToMarkdown() is

{ type: 'column_list', parent: '1. Column One\n\n', children: [] }

and subsequently, toMarkdownString() gives

1. Column One

The sublist item is missing completely.

Further detail showing that the blocks are correct coming from the Notion API:

This may be fixed in 3.1.1. (I was on 2.5.5.)
Investigating.

[andrew-polk]

Yes, this does seem to work in 3.1.1 so long as you don't have custom transformers (see #98).
