Update to 0.7.0.6

Changes from https://github.com/bos/aeson
0.7.0.6
 - Actually fix the DoS vulnerability by using the scientific parser
   (Parse a number using the new scientific parser)
     The old rational parser applied realToFrac (fromRational . toRational)
	 to the Scientific number to construct a new Scientific number. This
	 had
	 the disadvantage that scientific numbers with big exponents like
	 1e1000000000 are converted from (Scientific 1 1000000000) to
	 (Scientific (1*10^1000000000) 0). If the Integer coefficient of the
	 latter is later evaluated it will allocate all memory.

	 This is the first step needed to fix #198.
0.7.0.5
 - Bump attoparsec dep
 - Constrain the bounds on attoparsec and scientific
 - Update import location of scientificBuilder for v0.3.0.0
 - Add warning about space-usage on the Fixed instance
 - Use Scientific.toRealFloat instead of realToFrac in scientificToNumber
 - Renamed fromRealFloat back to fromFloatDigits
 - Use Scientific.fromRealFloat and Scientific.toRealFloat
 - Use floor on Scientifics again
   scientific-0.3 provides a DoS safe floor.
 - Use scientific >= 0.3.1
   scientific-0.3.1 exports the Text and ByteString Scientific Builders
   from the following modules respectively:
   - Data.Text.Lazy.Builder.Scientific
   - Data.ByteString.Builder.Scientific
0.7.0.3
 - Improve parseJSON failure message for Either
   This fixes #193.
 - Export `withScientific` function in `Data.Aeson`
   Fixes #191.
 - Reduce duplication, simplify CPP macros
