   Santa's Accounting-Elves need help balancing the books after a recent order. Unfortunately,
   their accounting software uses a peculiar storage format. That's where you come in.

   They have a JSON document which contains a variety of things: arrays ([1,2,3]), objects
   ({"a":1, "b":2}), numbers, and strings. Your first job is to simply find all of the numbers
   throughout the document and add them together.

   For example:

     • [1,2,3] and {"a":2,"b":4} both have a sum of 6.
     • [[[3]]] and {"a":{"b":4},"c":-1} both have a sum of 3.
     • {"a":[-1,1]} and [-1,{"a":1}] both have a sum of 0.
     • [] and {} both have a sum of 0.

   You will not encounter any strings containing numbers.

   What is the sum of all numbers in the document?

   Your puzzle answer was 191164.

--- Part Two ---

   Uh oh - the Accounting-Elves have realized that they double-counted everything red.

   Ignore any object (and all of its children) which has any property with the value "red". Do
   this only for objects ({...}), not arrays ([...]).

     • [1,2,3] still has a sum of 6.
     • [1,{"c":"red","b":2},3] now has a sum of 4, because the middle object is ignored.
     • {"d":"red","e":[1,2,3,4],"f":5} now has a sum of 0, because the entire structure is
       ignored.
     • [1,"red",5] has a sum of 6, because "red" in an array has no effect.

   Your puzzle answer was 87842.
