uniprot downloader: streaming requests etc

[bernt-matthias]

• use streaming requests and huge timeout (3600s) for allowing to download huge datasets (tested for 2.4GB which timed out before)
• add tabular output and column selector
• use reviewed filter for all input types not only for input_choice == common

For discussion:

• switch to standard select for the column selector?
  • I like the hierarchy, but select has the advantage to be searchable
  • linting fails due to incomplete xsd, I think...
• implement more advanced queries https://www.uniprot.org/help/query-fields?
