Fix the issue of duplicate unique ID for atoms using newtype.

The MergeFunctionsPass in LLVM merges identical functions (https://rust.godbolt.org/z/3nnr9nMne), resulting in the same function addresses.

 We can combine coroutines with [Fermi](https://docs.rs/fermi/latest/fermi/index.html) to emulate Redux Toolkit's Thunk system with much less headache. This lets us store all of our app's state *within* a task and then simply update the "view" values stored in Atoms. It cannot be understated how powerful this technique is: we get all the perks of native Rust tasks with the optimizations and ergonomics of global state. This means your *actual* state does not need to be tied up in a system like Fermi or Redux – the only Atoms that need to exist are those that are used to drive the display/UI.
