libcerf package and packing info out of date.

[Luke Benes]

On the package info site, https://tracker.debian.org/pkg/libcerf
The source URL and homepage are wrong and out of date. They should be 

homepage: https://computing.mlz-garching.de/
source URL: https://jugit.fz-juelich.de/mlz/libcerf

And the current version is 1.17: https://jugit.fz-juelich.de/mlz/libcerf/-/tags

The version in Debian, 1.3, is over 7 years old.  Can someone please update the info? 

Thanks
