public String getTargetURI() {
      return fields.get("WARC-Target-URI");
    }
The original URI whose capture gave rise to the information content in this record. In the
context of web harvesting, this is the URI that was the target of a crawler's retrieval
request. For a `revisit` record, it is the URI that was the target of a retrieval request.
Indirectly, such as for a `metadata`, or `conversion` record, it is a copy of the
`WARC-Target-URI` appearing in the original record to which the newer record pertains. The
URI in this value shall be properly escaped according to RFC3986, and written with no
internal whitespace.
@return The record's `WARC-Target-URI` header field, as a string.
