Naming of download files and tabular

[KimLothmann]

I don't know how feasible this is, but neither the download folder nor its table says anything about the data (I tested for receptors and cell densities).

We will take a look if we can implement something that allow the zip file to have more identifiable information.

We believe the file inside the zip (in this case, tabular.csv) does not need to have identifiable filename, since the sidecar file (readme.md) should contain the necessary metadata.
