[FEAT] Migrate to TypeScript

[MorningLightMountain713]

Is your feature request related to a problem? Please describe.
The codebase here is quite large. As someone browsing the code, it's pretty hard to figure out what is going on without typing. If Flux wants devs to be able to get up to speed quickly - this would be a lot easier if typing was used.

Describe the solution you'd like

• Add compile step in fluxnode build.
• Add pre commit hooks for linting / type checking.
• Slowly add in ts files over time.
• Profit

Codebase would be a lot more maintainable if TypeScript was used
