Use file-embed instead of hsb2hs to embed data files.

I think template haskell is robust enough now across platforms
that this will work.

Motivation: file-embed gives us better dependency tracking:  if a data
file changes, ghc/stack/cabal know to recompile the Data module.

This also removes hsb2hs as a build dependency.
