Provided compressed version of the downloadable files

[phax]

Bonus feature request: Support compression for the VERY large Peppol Directory export files. peppol_businesscards.csv is today 843MB large. gzipped it is only 42MB, a 95% reduction in file size. xz compressed it is even more compressed. You should consider keep on providing the uncompressed files with the current file names, for the sake of backwards compatibility for existing scripts where the current URL for the uncompressed version of the file is hard coded.
