Update data_sources

[bienflorencia]

The versions of some of the data sources for gnr_datasources() are out of date. The ones found here https://resolver.globalnames.org/data_sources.json
Is it possible to update them? Thanks!

I am planning to make an update in April or so. Do you have any specific resources you need to be updated?

Oh that's great and very much appreciated! I was using The Reptile Database when I realize of this (newest version here http://www.reptile-database.org/data/). Also IUCN Redlist would be fantastic, since their taxonomic names do not always match with ITIS ones. Kind regards,
