Automatically render emoji at appropriate sizes

In ./assets/2023-11-17-tribute-to-dr-raymond-peat.md I used a bunch of emojis. To get the right size relative to the text I used markdown's HTML passthrough to wrap each emoji in a div and individually size them.

This appraoch is verbose and repetative, but that's fine for unique problems. However, emoji's are nice to have, and a little work to do this automatically would go a long way.

Goldmark could automatically detect emojis in the markdown source, and automatically wrap each emoji in HTML to become the correct size. I found two sizes useful.

1. An mid-paragraph emoji should be around 1.5 times the normal font size.
2. Emoji only paragraphs should be 5 times the normal text size.

GoMoji looks useful.

• It has FindAll which returns a slice containing details about each emoji found in a string.
• And it has ReplaceEmojisWithFunc which we could use to wrap emoji's with custom HTML.
