errors only reported for one file at a time -- use `abortOnError: false`

Use abortOnError: false option. Don't expect to survive rollup errors though.

EDIT: this may not be a duplicate as abortOnError: false does do the trick, just could perhaps have a better DX. Since OP did not have a description and did not reply, hard to tell the intent.

See #168 for a feature request for the use-case of reporting all errors prior to aborting. It also had a branch commit added for it too (before going stale).
