<p>The producer_args passed by sqlt contains a number of keys which are<br>
not specific to JSON.  These were passed unfiltered to to_json().<br>
JSON (at least as of v2.90) will throw an error if it is passed an<br>
unknown option (it uses the option key as a method name, which leads<br>
to confusing error messages).</p>

<p>It's not straightforward to automatically determine the args supported<br>
by the JSON module, so this simply whitelist the 'pretty', 'indent',<br>
and 'canonical' options.</p>
