Add a test that checks the qZint generated barcodes are equal to those

Browse Source 
generated by libzint. Whether or not those barcodes are correct should be
validated in the test suite for libzint, for qZint it's good enough to
produce the same printouts that libzint does, which isn't trivial, especially
as some API names have different meanings, such as qZint ```text```
is libzint ```data```. Props Alonso Schaich <alonso@freebsd.org>
