* Use graal
* Use dynamic cores computer
* Use stream API to cleanup code
* Use max processors
* Use hash to avoid init string
* optimize concurrentmap init
* Smaller hash size
* Avoid checking concurrentmap
* Optimize data type
* string dedup
* Faster write
* Change base
* Remove time
* Use mul instead of div
* refactor: replace xtrace with "print_and_execute" function
* nit: stylize error messages
* replace out_expected.txt with measurements_1B.out
* print
* prevent errors on cleanup
* run tests and check warmup run output before running benchmark
* move "git diff" pretty diff output to test.sh
* Ensure "set -e" is re-enabled if we followed a "continue" branch
* add timeouts to test.sh invocations
* use diff with tocsv.sh to show differences on failed test
* add --quiet mode to test.sh
* move prepare_$fork.sh invocation to right below hyperfine since test.sh also invokes it
* Revert "add --quiet mode to test.sh"
This reverts commit 13e9fb7f395c1bd64a62528b8349803bc1366941.
* use tee to capture test output to a temp file and print contents on failure

* remove unneeded check
* slightly improved hash code perf
* Use unsafe to access memory + untangle the code a bit
* Adhoc cache that works a bit better
* Store station names as offset into the memory segment + length; slightly change how the hash is calculated

* Graal Native
* I need a GC :(
* Fix slash lolz
* Fix god damn output lol
I forgot java :D
* Custom hash, custom key
* More optimisations
* I don't need "optimize-build"
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

Prepare scripts that use `#!/bin/sh` and
`source "$HOME/.sdkman/bin/sdkman-init.sh"`
fail on systems where `sh` is not `bash`,
e.g. on Ubuntu it is `dash` which has not `source`.
