Rewriting the backend

[Sekky61]

Rewrite Tracking Issue

Implementation Tasks

• Implement base types of simulator #34
• RISC-V assembly parsing in Zig #41

Misc tasks

• Initialize the Zig project #32
• CI tests for Zig simulator #38
• Setup WASM build of the simulator #40
• Add fuzzing to the simulator #42
• Implementation of core blocks with central controller #43

Description

I feel like backend implementation is holding the simulator back on several axes:

• performance
• API protocol
• caching

Arguably, caching could be implemented in Java. But as for the others, not so much.
Especially since I am not a Java expert.

Long story short, rewrite it in Zig!

Wishlist from v1 (Java):

• Pipelined functional units
• Instruction cache (?)
• Works client-side, no server calls (WASM)
• Proper testing

Design

Modelling memory

The memory is modelled as a collection of pages.
