Evaluate viz code via Wrattler plugin

[rolyp]

Minimal Wrattler integration, based on Tomas' example. Preliminaries:

• [x] read Docker documentation
• [x] skim JupyterLab documentation
• [x] check Wrattler running with docker-compose
• [x] check local file changes are visible inside container
• [x] sort access problem pushing to repo
• [x] enable Merger plugin
• [x] enable variant of Merger with Monaco editor
• [x] publish viz language to npm as package @rolyp/fluid
• [x] skeletal Fluid plugin
• [x] fix icon colour
• [x] distinguish icon colour from Racket
• [x] export TypeScript module from @rolyp/fluid
• [x] Evaluate! button
• [x] parseWithImports not resolving to a function:
  • [x] upgrade @rolyp/fluid to recent versions of webpack and webpack-dev-server
  • [x] revisit library, libraryExport and libraryTarget properties of webpack.config.js
  • experiment with resolve.modules
  • [x] experiment with require rather than import on client side
  • drop back to single library target
• [x] loadModule statements in Module.ts should find files - put in Wrattler public folder for now
• [x] evaluate result of parsed source
• [x] puppeteer npm installation problem
• [x] clean up npm of @rolyp/fluid (whitelist files)
• [x] licence for npm package

• [x] can I delete empty languagePlugins folder?
• [x] how to I edit wrattler.github.io pages?
