  integers more efficiently (https://github.com/bos/aeson/issues/198)

0.11.2.0

* The new Chunk typeclass allows for some code sharing with Ed
  Kmett's parsers package: http://hackage.haskell.org/package/parsers

* New function runScanner generalises scan to return the final state
  of the scanner as well as the input consumed.

  numbers much more efficiently.

  single-character lookahead.
