Write CSVs from remotely read package to disk

[peterdesmet]

One can read a Data Package (read_package()) from a URL or download it first and then read it locally.

The current behaviour for writing a remotely read package is to not copy the files to disk, since they are already available online. However, that makes it more difficult to 1) download a whole Data Package using R and 2) update a Data Package (e.g. adding a resource), because the originally local paths are now URLs pointing to an online CSV, and that might not be the version you want to point to.
