Switch over to the WABT bindings generated by wit-pack

[Michael-F-Bryan]

This is waiting on https://github.com/wasmerio/wapm.io-backend/issues/240.

[Michael-F-Bryan]

I've updated this to use the wasmer/wabt package from wapm.io on my computer, but it looks like I've lost write access to the repo. @syrusakbary can you add me to the repo again?

Also, how do I test this?

[syrusakbary]

npm run test should test things locally @Michael-F-Bryan

It currently fails:

I've added the "dom" lib to the lib field inside of tsconfig.json.

And then we got other error:

> npm run compile && node ./node_modules/vscode/bin/test

After fixing the file manually importing Bindings as BaseBindings I got things compiling:

// @ts-ignore
import { Wasi } from "@wasmer/wasi";
import { Bindings as BaseBindings } from "./bindings/bindings";

/**
 * Options used when initializing the bindings.
 */
export type LoadOptions = {
    /** Additional imports to be provided to the WebAssembly module */
    imports: WebAssembly.Imports,
    /**
     * A user-specified WebAssembly module to use instead of the one bundled
     * with this package.
     */
    module: WebAssembly.Module,
};
/**
* Extended options used when loading a WASI library.
 */
export type WasiLoadOptions = LoadOptions & {
    /** An initialized `@wasmer/wasi` object. */
    wasi: Wasi,
};

export default class Bindings {
    bindings(options?: Partial<WasiLoadOptions>): Promise<BaseBindings>;
}

The npm run test command currently fails because we've got no test/ directory. I'm assuming that just means someone deleted the repo's tests in the past. I'm inclined to merge this as it is now because everything builds, and I'll fix #41 in a separate PR.
