Producer for data URIs.

<p>Data URIs embed the data in the URI itself. They don't point to a file location; the URI is
the data. Data can be encoded in either base-64 or escaped ASCII. See the <a
href="http://tools.ietf.org/html/rfc2397">spec</a> for full details.

<p>Data URIs are intended for small pieces of data only, since the URI lives on the Java heap.
For large data, use a another URI type.

<p>Charsets specified in the URI are ignored. Only UTF-8 encoding is currently supported.
