and drop the now unused extract_lists function
this also fixes a bug, where we did not add the datastore to the list at
all when there was no rrd data

there is now a 'extract_cached_data' which just returns
the data of the specified field, and an api function that converts
a list of fields to the correct serde value
this way we do not have to create a serde value in rrd/cache.rs
(makes for a better interface)

this is an interface to simply get the Vec<Option<f64>> out of rrd
without going through serde values
we return a list of timestamps and a HashMap with the lists we could find
(otherwise it is not in the map)
if no lists could be extracted, the time list is also empty
