Subject: Set plaintext offset to 0 when writing J2K frames (DoM #2391)

Without this the EasyDCP verifier gives errors like

"sum of individual components is larger than the file size"

This change results in there being no plaintext metadata in each
encoded frame.  It looks like the DCP-2000 was fixed in around
2010 to not crash with plaintext metadata, and the asdcplib tools
at some point started defaulting to this behaviour also.
