Zugferd importer does not recognize XRechnung Zugferd Profile

[Sarenor]

A PDF with an embedded XRechnung like this

<ram:GuidelineSpecifiedDocumentContextParameter>
    <ram:ID>urn:cen.eu:en16931:2017#compliant#urn:xeinkauf.de:kosit:xrechnung_3.0</ram:ID>
</ram:GuidelineSpecifiedDocumentContextParameter>

is recognized as a valid Zugferd Document, but no Profile could be found for it. Would it make sense to change the getZugferdProfile() method in the ZUGFeRDImporter.java

    public String getZUGFeRDProfil() {
        switch (this.extractString("//*[local-name() = 'GuidelineSpecifiedDocumentContextParameter']//*[local-name() = 'ID']")) {
            case "urn:cen.eu:en16931:2017":
            case "urn:ferd:CrossIndustryDocument:invoice:1p0:comfort":
                return "COMFORT";
            case "urn:cen.eu:en16931:2017#compliant#urn:factur-x.eu:1p0:basic":
            case "urn:ferd:CrossIndustryDocument:invoice:1p0:basic":
                return "BASIC";
            case "urn:factur-x.eu:1p0:basicwl":
                return "BASIC WL";
            case "urn:factur-x.eu:1p0:minimum":
                return "MINIMUM";
            case "urn:ferd:CrossIndustryDocument:invoice:1p0:extended":
            case "urn:cen.eu:en16931:2017#conformant#urn:factur-x.eu:1p0:extended":
                return "EXTENDED";
            // new addition
            case "urn:cen.eu:en16931:2017#compliant#urn:xeinkauf.de:kosit:xrechnung_3.0":
                return "XRECHNUNG";
            default:
                return "";
        }
    }

Or would it be better to fold this into EXTENDED?

sounds like a very good idea👍, actually it would be sufficient to scan for "xrechnung" in the guideline ID to return XRechnung, no need to restrict to version 3...

That would mean breaking up the switch, probably, but that's fine. I'll try to send in a PR later today.
