Cjs named import

[dmail]

This PR tries to make esm capable to use named import on cjs files.
Unfortunately the issue seems complex and the actual fix should wait until I get feedback from rollup team.

PR ready to merge with the following changes

21.1.0

• Improve MISSING_EXPORT error during build
  • Log correct file urls
  • Suggest to use commonJsToJavaScriptModule when it seems needed
• Write tests consuming cjs in esm
• Open issue in rollup plugin [@rollup/plugin-commonjs] MISSING_EXPORT when cjs re-export an other file rollup/plugins#1011
• Regroup some tests together
• Update some deps
