Dutch qr decode failed. It's using a custom base45 encryption

Hi.. I cannot decode a dutch QR code with it as it uses a custom base45 variant.
 
You can read more about it here: https://www.bartwolff.com/Blog/2021/08/21/decoding-the-dutch-domestic-coronacheck-qr-code

Is there a possibility to add something so that dutch codes also work?

Thanks in advance!
