Gs1Parser class abstract final

Parses GS1-128, GS1 DataMatrix, GS1 QR and GS1 DataBar data.

Accepts element strings with FNC1 as the ASCII group separator \u001D (how camera decoders and most scanners deliver it), with or without a leading symbology identifier (]C1, ]d2, ]Q3, ]e0) or leading separator, and the human readable form with parentheses.
