Improvement in CalculateAverage_yavuztas (#162)
* improve double reading by eleminating string parsing in between, make calculations over on integer instead of double, parse into double at the end only once * more improvements, sharing a single StringBuilder to build all toStrings, minor performance gain. * micro optimizations on reading temperature * a small skip for redundant traverses, micro optmization * micro optimization, eleminate some if cases, saves 0.5 seconds more * micro optimization, calculate key hash ahead eleminates more more loop, saves 0.5 seconds more :) * optimize key equals and handling the case when a region is larger than max integer size --------- Co-authored-by: Yavuz Tas <yavuz.tas@ing.com>
