Title: Adds lines for cleaning data

Most of it is parsing times and recognise missing data, e.g. an empty string to `NA`.

Some codes do not yet make sense to me, so this is by far no final. Have a look to see how this would work.

We ought to reduce the number of columns; I can't imagine that all of those are useful.
