Support calling GroupBy#each_group w/o blocks #443

Closed hibariya closed 6 years ago

Hi, I’ve had GroupBy#each_group without blocks return an Enumerator. Other each* methods in daru seem also returning an Enumerator. I think it looks useful and natural as Ruby. What do you think?

This may be related to #145.
