Base64QRCode class seems to be missing from the latest build

Base64QRCode class seems to be missing from the Nuget package, is it depracated or new ?

same issue as this #442

[artizani]

figured this is due to the breaking changes in net 6. Simply convert byte array to base64 natively and ignore this file

This is fixed with #495 and will be part of QRCoder 1.5.0.
