Something like `datasette-export` which adds a `export` command using https://docs.datasette.io/en/stable/plugin_hooks.html#register-commands-cli - then you could run:

    datasette export my-export-dir mydatabase.db -m metadata.json --template-dir templates/

And the command would then:

- Create a `Datasette()` instance with those databases/metadata/etc
- Execute`await datasette.client.get(""/"")` to get the homepage HTML
- Parse the HTML using BeautifulSoup to find all `a[href]`, `link[href]`, `script[src]`, `img[src]` elements that reference a relative path as opposed to one that starts with `http://`
- Write out the homepage to `my-export-dir/index.html`
- Recursively fetch and dump all of the other pages and assets that it found too

All of that HTML parsing may be over-complicating things. It could alternatively accept options for which pages you want to export:

```
datasette export my-export-dir \
  mydatabase.db -m metadata.json --template-dir templates/ \
  --path / \
  --path /mydatabase ...
```

Or a really wild option: it could allow you to define the paths you want to export using a SQL query:

```
datasette export my-export-dir \
  mydatabase.db -m metadata.json --template-dir templates/ \
  --sql ""
select '/' as path, 'index.html' as filename
  union all
select '/mydatabase/articles/' || id as path, 'article-' || id || '.html' as filename
from articles
  union all
select '/mydatabase/tags/' || tag as path, 'tag-' || tag || '.html' as filename
from tags
""
```
Which would save these files:
- `index.html` as the content of `/`
- `article-1.html` (and more) as the content of `/mydatabase/articles/1`
- `tag-python.html` (and more) as the content of `/mydatabase/tags/python`","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1108671952,
