[bug] Content Publishing Service should write bytes not ascii bytes to the content hash field of the parquet file

[wilwade]

Per the dsnp spec, write the bytes of the hash not the ascii bytes of the hash to the content hash column of the batch files.

• Fixed in Content Publishing
• Checked that it is correctly read in Content Watcher and correctly re-encoded in responses
• Checked in SAT to make sure it is also handling it correctly
