Vcard V4

[prosperot]

I am experiencing a lot of problems with your vcard implementation. The cards generated don't follow the Vcard standards : https://docs.fileformat.com/email/vcf/

Maybe its a good idea to go to Vcard version 4: https://github.com/jeroendesloovere/vcard/tree/2.0.0-dev
