One of the great things about semgroup over x/sync/errgroup is that it actually waits all tasks to complete and returns an error. However, the returned error type doesn't let the caller to iterate over the errors (e.g. my use case requires me to truncate the list of errors). Therefore, introducing a backwards-compatible change that exports `MultiError` type, and guarantees that `Wait()` method returns an error of this type.

LGTM, I believe I didn't expose it deliberately to force the caller to use |
