Update build & tests systems

[Glinkis]

• Replaces @rollup/plugin-babel, @rollup/plugin-json, rollup-plugin-terser, and @rollup/plugin-replace with rollup-plugin-esbuild-transform, which massively speeds up the compilation.

• Extracts rita & sentry into separate bundles.

• Replaces ts-jest with esbuild-runner, which massively speeds up the tests as well.

• Updates all node scripts to typescript.

Benchmark summary:

Build: ~25s to ~5s
Tests: ~20s to ~3s
