Doesn't load on julia 0.6

This is what I get on julia 0.6 right now:

I think something in the recent FlatBuffers updates broke things. If I fix FlatBuffers at v0.2.0, things seem to work.

Should we maybe as a short-term solution just put upper bounds on FlatBuffers for all the registered versions of Feather.jl in METADATA.jl?

Got the same error.

Not sure how do to fix FlatBufffers? Can't seem to find resources on initial google so have aksed on stackoverflow

Works on Feather master (with DataFrames master)

Should be fine now on 0.6 w/ the new Metadata upper bounds.
