Fix : LZWEncode filtyer template didn't provide a set_defaults method.
DETAILS :
A problem happens when converting comparefiles\PT.ps with ps2write :
an encoded stream could not decode. The reason is that pdf_flate_binary
did not set defaults to LZWE template.
1. Provided a set_defaults method (fixes pdf_flate_binary).
2. Used it instead an old hack in gdevpsdi.c (a minor improvement).
EXPECTED DIFFERENCES :
None.
