wasm-forceatlas2 v0.1.1

Important: Only supports nightly. It is currently set with the following command: https://github.com/wasm-tool/wasm-pack-plugin/issues/95#issuecomment-778031088

Based on the Rust forceatlas implementation (forceatlas2), this is a binding between js and the Rust implementation. The long term plan is to create a faithful implementation of the Graphology - forceatlas2 npm library to serve as a drop-in replacement of the pure JavaScript implementation with a better performance.
