v0.3.0 - Preliminary Kusama compatibility

This is a pre-release compatible with the Polkadot v0.8 runtime API and the Kusama network.

New Features

• compatible with Polkadot v0.8 runtime API (go-wasmer)
• networking up-to-date with substrate as of Feb 25 2021 (discovery, message exchanges tested and working with Kusama)
• compatibility with polkadot.js: implement storage and chain updates via websocket; able to query blocks and state; account and extrinsic submission working within node.js
• add preliminary support for the perlin/life wasm interpreter

• network improvements based on CPU profiling; read/write directly to/from same stream when syncing, improve allocations
• syncing algorithm improved to queue block data while currently processing data
• basic scoring and pruning added to sync algorithm; don't disconnect from preferred peers

Bug Fixes

• runtime upgrades fixed and tested with Kusama
• runtime bug where values were not being correctly copied before placed into trie fixed
• use __heap_base as allocator offset for runtime
• fix BABE threshold calculation to match substrate
