refactor(theme/book): Split into modules (#556)
Advantages: - Easier to reason about - Can easily disable some modules when debugging - Shared dependencies are explicit (playpen_text) - Enables some fancier things later one (e.g. run `codeSnippets` slightly later, to avoid blocking the page) I'm aware that `codeSnippets` should be split into the highlighter and the editor, but I'm not sure I understand exactly how they interact so I've left it as it is for now.
