* Graal Native
* I need a GC :(
* Fix slash lolz
* Fix god damn output lol
I forgot java :D

I don't care about image size! :D
- Eliminate redundant object creations in between
- Custom HashMap on purpose - Inspired by @spullara
- More performant temperature parsing - Inspired by @yemreinci
- JVM tweaks, decreased heap memory, and remove AlwaysPreTouch
