message: core: allow to be bundled again
  regressed in last version. added comment explaining why no import
diff: -import { ResolverFactory } from 'enhanced-resolve';
  import path from 'path';
  import { cachedProcessFile, FileProcessor, MinimalFS } from './cached-process-file';
  import { safeParse } from './parser';
  import { process, processNamespace, StylableMeta } from './stylable-processor';
  import { timedCache, TimedCacheOptions } from './timed-cache';
  +// importing the factory directly, as we feed it our own fs, and don't want graceful-fs to be implicitly imported
  +// this allows @stylable/core to be bundled for browser usage without special custom configuration
  +const ResolverFactory = require('enhanced-resolve/lib/ResolverFactory') as typeof import('enhanced-resolve').ResolverFactory;
