Fix segfault caused by uninitialized `cluster.series.timeseriesNumber…

…s` (#1876)

```cpp
void Area::resizeAllTimeseriesNumbers(uint nbYears) 
{ 
    assert(hydro.series and "series must not be nullptr !"); 

    load.series.timeseriesNumbers.reset(1, nbYears); 
    solar.series.timeseriesNumbers.reset(1, nbYears); 
    wind.series.timeseriesNumbers.reset(1, nbYears); 
    hydro.series->timeseriesNumbers.reset(1, nbYears); 
    for (auto& namedLink : links) 
    { 
        AreaLink* link = namedLink.second; 
        link->timeseriesNumbers.reset(1, nbYears); 
    } 
    thermal.resizeAllTimeseriesNumbers(nbYears); // resize is called here
    renewable.resizeAllTimeseriesNumbers(nbYears); // resize is called here
}
