fixes #314

@wurzka @Markus1812 The failing test runs successfully when I run it locally with ABAP Unit. Do you have any ideas why it might fail in the gh action?

add a skip to https://github.com/SAP/abap-file-formats-tools/blob/fix-regex-escape-sequences/test/abap_transpile.json#L55 to make the unit tests succeed, I spend some time yesterday to try fixing the regex, but too much escaping of stuff
