Wrap emojis in span nodes (#4759) Text.Pandoc.Emoji now exports `emojiToInline`, which returns a Span inline containing the emoji character and some attributes with metadata (class `emoji`, attribute `data-emoji` with emoji name). Previously, emojis (as supported in Markdown and CommonMark readers, e.g ":smile:") were simply translated into the corresponding unicode code point. By wrapping them in Span nodes, we make it possible to do special handling such as giving them a special font in HTML output. We also open up the possibility of treating them differently when the `--ascii` option is selected (though that is not part of this commit). Closes #4743.

Test that emojis are wrapped in Span
```
% pandoc -f commonmark+emoji -t native

Use pretty-simple to format native output. Previously we used our own homespun formatting. But this produces over-long lines that aren't ideal for diffs in tests. Easier to use something off-the-shelf and standard. Closes #7580. Performance is slower by about a factor of 10, but this isn't really a problem because native isn't suitable as a serialization format. (For serialization you should use json, because the reader is so much faster than native.)

Switch from pretty-simple to pretty-show for native output. Update tests. Reason: it turns out that the native output generated by pretty-simple isn't always readable by the native reader. According to https://github.com/cdepillabout/pretty-simple/issues/99 it is not a design goal of the library that the rendered values be readable using 'read'. This makes it unsuitable for our purposes. pretty-show is a bit slower and it uses 4-space indents (non-configurable), but it doesn't have this serious drawback.
