[Lognorm] Escape [ and ]

 And, probably, there is mismatch:

$ cat num.txt 
num: 42

$ cat num.rb
rule=:num: %answer:number%

$lognormalizer -r num.rb -e json < num.txt 
{ "answer": "42" }

But if i read on  https://en.wikipedia.org/wiki/JSON

JSON's basic types are:
*  Number: a signed decimal number that may contain a fractional part and may use exponential  E notation . JSON does not allow non-numbers like  NaN , nor does it make any distinction between integer and floating-point. (Even though JavaScript uses a  double-precision floating-point format for all its numeric values, other languages implementing JSON may encode numbers differently)
*  String : a sequence of zero or more  Unicode characters. Strings are delimited with double-quotation marks and support a backslash  escaping syntax.

So, i think lognorm return wrong JSON. This is must be without double quotes:
{ "answer": 42 }

Is this expected behavior?
