Add three Java source files that enable SGTIN-96 EPC generation
directly from within the DELIVERY.xsl transformation:
- Gs1EpcEncoder.java: encodes SGTIN-96 (38-bit serial via MD5) and
SGTIN-198 (140-bit ASCII serial); serial derived from MD5(DOCNUM+POSNR+counter)
- Sgtin96Function.java: Saxon-HE ExtensionFunctionDefinition that
registers gs1:encodeSgtin96FromIdoc() for use in XSLT
- TransformAndEncode.java: Saxon s9api runner that registers the
extension and executes DELIVERY.xsl in a single pass
Also update .gitignore to track java/src/ while continuing to exclude
compiled output in java/bin/.
