Bug#1109844: Updating to version 2.01

[David Cook]

Package: libgd-barcode-perl
Version 2.00

GD/Barcode/QRcode.pm generates an "uninitialized" warning. This issue was
fixed upstream in March 2024, and the code maintainer has just uploaded an
updated version 2.01 to CPAN.

Could we get an updated Debian package with the new version? The changes
between 2.00 and 2.01 are pretty minimal, so hopefully it should be easy.
Maybe even worth a backport. 

Many thanks!
