notionic v0.13.0

Minor Changes

• #53 377f0a1 Thanks @nublson! - Demo embeds take a height: …/demos/<name>?height=320 makes the demo's frame 320px tall, border included, with the demo centered and no vertical padding, so short frames stay as short as asked. Notion's API doesn't send the size an embed is given in Notion, so the URL carries it. Custom frames get it as the height prop (undefined without one); the default frame still fits the demo when there's none.

• #52 0939992 Thanks @nublson! - Headings now render at their Notion level instead of one level down: heading 1 is <h1>, heading 2 <h2>, heading 3 <h3> and heading 4 <h4>, and blocksToMarkdown writes # through ####. The footnotes title follows its marker heading the same way. If your page title is also an <h1>, use heading 2 and below in Notion for sections.
