Release v3.0.1

Fix issue with Webpack v4.

Release v3.0.0

Notable changes

• The library is now compiled to WASM, which shrinks the file size (Viz.js
  (2.1.2 full version) brotlified: 409K; @aduh95/viz.js (3.0.0-beta.7 browser
  version) brotlified: 337K; 18% decrease), should improve performances and
  allows dynamic memory growth.
• The JS code is now transpiled from TypeScript, and typings are packed within
  the npm package. You can find the API documentation there!
• The library is able to reset its internal error state, which makes the
  v2 wiki caveat
  unnecessary.
• Rendering from main thread is no longer supported on the default async API,
  you must use a worker (webworker or worker_thread).
• There is a synchronous version available for legacy Node.js support.

Breaking changes and deprecations

• BREAKING: Bump required version of Node.js to v12.17.0+. Older Node.js
  version may support the synchronous API.
• BREAKING: Remove Viz.prototype.renderSVGElement. You can use
  renderString and DOMParser to achieve the same result.
• BREAKING: Remove Viz.prototype.renderImageElement. You can use
  renderString and Canvas to achieve the same result.
• BREAKING: Remove Module and render from Viz constructor's options
  (you must now specify either worker or workerURL).
• BREAKING: Remove lite version, Viz.js now comes in only one variant.
• BREAKING: The full.render.js script is replaced by the render.node.mjs
  and render.browser.js modules.
• BREAKING: The render.node.js module (that replaces full.render.js)
  exports a worker_thread factory when imported from the main thread. It's
  available through @aduh95/viz.js/worker specifier on Node.js and bundle
  tools that support package.json#exports.
• BREAKING: The render.browser.js module (that replaces full.render.js)
  exports a function which takes a Module object as parameter. You should use it
  to give the path to render.wasm the Emscripten script. You should not import
  this module from the main thread. On bundle tools that support
  package.json#exports, you can use the specifier @aduh95/viz.js/worker.
• BREAKING: Compiles to WebAssembly, which cannot be bundled in the
  render.js file like asm.js used to. Depending on your bundling tool, you may
  need some extra config to make everything work. You might also use the
  synchronous API, which bundles the asm.js code, although its usage should be
  strictly limited to Node.js or webworker use.
• BREAKING: Remove ES5 dist files, all modern browsers now support ES2015
  modules. If you want to support an older browser, you would need to transpile
  it yourself or use an older version.
• BREAKING: On Node.js, require('@aduh95/viz.js') returns now a
  Promise<Viz>.
• DEPRECATED: require('@aduh95/viz.js') is deprecated, use
  import('@aduh95/viz.js') instead.

Added features

• Add support for Node.js worker_threads.
• Refactor JS files to TypeScript.
• Refactor viz.c to C++ to use
  Emscripten's Embind.
• Use ALLOW_MEMORY_GROW compiler option to avoid failing on large graphs.
• Improve error handling:
  • Rejects with the full error string from Graphviz.
  • Remove the need of creating new instances when render fails by resetting
    internal error state.
• Switch to Mocha and Puppeteer for browser testing.
• Add synchronous API using asm.js (@aduh95/viz.js/sync).
• Add a helper module for asynchronous API (@aduh95/viz.js/async).
• Upgrade deps:
  • Upgrade Emscripten to 1.39.16
  • Upgrade Graphviz to 2.44.0
  • Upgrade Expat to 2.2.9
  • Upgrade Rollup to 2.x
• Change test chain:
  • Upgrade Mocha to 7.x
  • Use Puppeteer instead of Selenium
