Description
Hello, I'm using this great package to do basic data operations, and just found myself wanting to get back an OrderedDict from DataStructures.jl, since the order in which values appear in the iterable is significant.
I see there's some type promotion optimization going on in the group code, and I wonder if it would be possible to support passing in or otherwise specifying the output type in a way that preserves good type information.
Thanks for your work on this package!

Research direction
Start by locating the group implementation and its type-promotion logic in SplitApplyCombine.jl. Determine how an output collection type could be specified while preserving iterable order and useful type information; done means the proposed behavior is implemented and covered by tests, though no test file is named in the issue.
