If I try to simply include microformats using the script tag provided in the readme, I can only get CID, bytes, digest, hasher and varint:

<script src="https://unpkg.com/multiformats/dist/index.min.js"></script>
<script>
console.log(Multiformats);
</script>

Either the README misses something, or the dist/index.min.js does! For instance how can I get codecs from multiformats/codecs?
