add to Stackage

[juhp]

It would be nice to add content-store to Stackage Nightly and LTS.

Currently in for Nightly:

conduit-combinators-1.3.0 is out of bounds for:

• content-store-0.2.1 (>=1.1.0 && < 1.3). Used by: library, test-suite

resourcet-1.2.1 is out of bounds for:

• content-store-0.2.1 (>=1.1.9 && < 1.2). Used by: library, test-suite

[juhp]

Because of above content-store fails to build for LTS 11 and LTS 12.
Note that conduit-combinators has been merged into conduit as of 1.3.

Overriding the resourcet bound leads to:

Data/ContentStore.hs:120:41: error:
    • No instance for (MonadBase IO (ResourceT (ExceptT CsError IO)))
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
    • When deriving the instance for (MonadBase IO CsMonad)
