Improvements

• stable naming of functions and tests
• multi-line test source instead of manual append calls
• switch places for equals comparison in tests, figure out the comptime error cause (ziglang/zig#4437)
• named structs as function results in day2
• use test allocator in prod code as arg to verify no leaks occur
• try different allocators (arena maybe?)

Days I reached out for help

• day 8, part 2 (decision to use LCM)
• day 18, part 2 (Pick's theorem and Shoelace formula)
