Update availability parameters
Currently there is
- p_gnu -> availabilityCapacityMargin to say how much capacity contribution unit can make to each connected node
- p_unit -> availability is used in most places as a constant availability modifier. This should rather be time series.
- p_unit --> becomeAvailable and becomeUnavailable (or other way around) can set availability start/stop once for the model run.
- ts_unavailability (not used in main model - Jussi's addition)
- ts_cf availability of flow units
- ts_unit --> unavailability (from Niina's comment below)
- ts_gnn --> availability for the availability of transfer connections (New addition by Niina). Accompanied by a flag useTimeseriesAvailability in p_gnn. It would seem that this is a model how things should be done for units too.
There should be a better way.
