here's how to handle column support

[GorvGoyl]

I needed to show 2 images in one row (2 columns), but it isn't directly possible. Currently, content in columns is rendered as individual rows. I figured out a way to show it in columns as how it is shown in Notion.

n2m.setCustomTransformer("column_list", async (block) => {
    const mdBlocks = await n2m.pageToMarkdown(block.id);
    const mdString = n2m.toMarkdownString(mdBlocks);
    return `
    <div style='display:"flex";column-gap:"10px"'>
   ${mdString}
    </div>
    `;
  });
n2m.setCustomTransformer("column", (block) => {
// avoid rendering it twice
    return "";
  });

I thought of sharing it in case others are looking for same.
