Constrain vector <0.13 for store's sake.

[philderbeast]

I need to constrain vector < 0.13 in order to build store otherwise I get errors like:

src/Data/Store/Internal.hs:824:3: error:
    • No instance for (Store (Data.Vector.Unboxed.Base.Vector b))
        arising from a use of ‘peek’

Looking at vector-0.13 release notes, this is the breaking change:

• Remove redundant Storable constraints on to/from ForeignPtr conversions: #394

I first encountered this on ucsd-progsys/liquid-fixpoint#609

Thanks for the PR!

Instead of adding this upper bound, I'm fixing this instore-0.7.16 by skipping generation of these instances which aren't very useful.

This actually is not caused by a breaking change in vector - vector#378. TH allows you to reify information about other packages in such a way that internal changes can cause breakage.
