Save everything to localStorage

[steveRoll-git]

Other than the assembly code, also store the following things in localStorage and load them when the app loads:

• Initial PC
• Initial registers
• Placed nodes
• Set memory (if implemented)

Switching to Jotai might help make this easier because it can store atoms in localStorage automatically

I dont think thats a good idea, imagine if the user leaves the site, returns, and gets weird output because he forgot he set a register $28 to something customized, or he forgot the node set up in Jmp addr wire.
