Multiline Input

[robinrosenstock]

Thank you very much Giulia for making react-qrcode-logo and this example project.
Because I'm not familiar with react (and because of convenience) I used your example application QRCodeCustomizer. I wanted to create a QRCode, which holds a VCARD.
Unfortunately this does not work, because the "value" input field is only singleline and for a VCARD you have to enter a multiline value (I've tried with newline escape characters, which didn't work).
