biggest refactor ever...

- use kxs-ts-gen for TypeScript schemas
- update schema files, so they're tidier (no need for typescript-generator workarounds)
- version bumps (kotlin, gradle, tstl, factorio, kotest)
- improve kxs binary format (use okio)
- move schema files package ('events' wasn't needed)
- tidy up topic creation, naming. base it off classes, make util functions
