 Update `binary` submodule in an attempt to address #9630

 This removes a couple of `INLINE` pragmas from the generics helper
 classes. With this change the compile times and memory usage should
 go back to the previous GHC 7.8.3 situation.

 This has been submitted upstream as
 https://github.com/kolmodin/binary/pull/62
