ESM: avoid critical dependency webpack warning

[floryst]

Context

When using the @kitware/vtk.js package, webpack users would run into a Critical dependency warning, like the one below.

WARNING in ./node_modules/@kitware/vtk.js/_virtual/commonjsHelpers.js 154:8-29
Critical dependency: the request of a dependency is an expression
 @ ./node_modules/@kitware/vtk.js/_vendor/readable-stream/lib/_stream_duplex.js_commonjs-dynamic-register 4:0-77 6:0-16
 @ ./node_modules/@kitware/vtk.js/Rendering/Core/Actor.js 2:0-87
 @ ./src/index.js 10:0-60 50:14-34

Changes

We switch to using the polyfill rollup plugin in order to polyfill out stream (and readable-stream).

Results

Initial testing indicates that the polyfill works and the error does not occur in webpack builds that consume @kitware/vtk.js.
