v2 - no prod deps, less window calls

Breaking

• instead of setting ImageResizor.QuillFind set ImageResizor.Quill = Quill when using es6 imports

Misc

• no prod deps
  • kicked out lodash -> reduced bundle size by almost 50%
  • quill is now just a peer dependency
• reduced window['Quill'] access
• more safety checks, if things are defined as expected
• update deps
