Library for deserializing rows in `postgresql-simple` (or any other

library that uses `FromRow`) based on column names instead of the

positions of columns.

## Example

```haskell

{-# LANGUAGE DeriveGeneric #-}

import           Database.PostgreSQL.Simple.FromRow

import           Database.PostgreSQL.Simple.FromRow.Named

import qualified GHC.Generics as GHC

import           Generics.SOP

data Foobar = Foobar

  { foo :: !String

  , bar :: !Int

  } deriving (Show, Eq, Ord, GHC.Generic)

instance Generic Foobar

instance HasDatatypeInfo Foobar

instance FromRow Foobar where

  fromRow = gFromRow

```
