* 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

* A solution with Actor Model concurrency and MappedByteBuffer
* fix test cases
* revert back the file name to original
* cache String hashCode calculation via composing with Key object
* fix wrong key caching and eleminate duplicate String creation between actors
* update possible char count in a line, fix calculate_average.sh
* increase possible line length to 256 bytes, much safer to cover 100 chars I hope
