de3f60861d Fix hitdetection of icons with opacity < 1
Hit detection works by reading the pixel color, if the icon is not drawn
with full opacity it won't work.

8645a3109d Fix zIndex handling for hitdetection
getZIndex returns number|undefined, so Number conversion is unnecessary, but
undefined was converted to NaN instead of zero.

49c6ab716c Fix VectorLayer hitdetect inaccuracy
Due to rounding the hitdetection may have been off by one pixel.
At map edge the pixel coordinate may exceed the map's dimensions if an
decimal pixel ratio is used, this is fixed by clamping to the canvas
dimensions.

054af09032 Make code prettier
This updates ESLint and our shared eslint-config-openlayers to use Prettier.  Most formatting changes were automatically applied with this:

    npm run lint -- --fix

A few manual changes were required:

 * In `examples/offscreen-canvas.js`, the `//eslint-disable-line` comment needed to be moved to the appropriate line to disable the error about the `'worker-loader!./offscreen-canvas.worker.js'` import.
 * In `examples/webpack/exapmle-builder.js`, spaces could not be added after a couple `function`s for some reason.  While editing this, I reworked `ExampleBuilder` to be a class.
 * In `src/ol/format/WMSGetFeatureInfo.js`, the `// @ts-ignore` comment needed to be moved down one line so it applied to the `parsersNS` argument.
