## http_get_extract_by_title
The following:
 - decompresses the file into a pipe
 - transforms the base64 encoded data in the 'data' field using the DAP 'transform' filter
 - uses the DAT 'decode_http_reply' filter to decode the HTTP response
 - emits this as JSON
 - Uses jq to check the '.data.http_title' field for "Invalid URL" (sorry for the dots in the name)
 - uses pigz to compress the stream into an output file so that you don't have to store uncompressed data at any point.
