0.8.0 - WASM x Zephyr refactor

Release Overview

Previous releases have been incrementally refactoring the VM's code, yet the technical debt has kept increasing.
This release introduces a huge refactor of the VM's code base to eliminate much of this technical debt.

The refactor is centered around:

• add missing features of the latest WASM spec (focussed on version 2)
• improve testing (many bugs have been fixed in latch)

The release is also a major step towards Zephyr as main platform (#290).
