  update Integration section of README to reflect latest version in SPM usage subsection
  Fix duplicate comma typo
  update readme
  make casting nil to nsnull optional
  represent strings with nil as if it was nsnull
  Instead of checking for the Int8 type explicitly when setting 'object', cast the Int8 value to an Int and pass that into an NSNumber when setting 'int8' or 'int8Value'
  Update version in pod spec
  Add performance test
  Attemp to fix #697
  Fix 'AnyObject' in comment and README.md
  The ‘isBool’ function on the NSNumber extension uses ‘trueObjCType’, which represents the type encoding for ‘true’ represented as an NSNumber, and ‘falseObjCType’, which represents the type encoding for ‘false’ represented as an NSNumber. Both type encodings are equal to ‘c’. However, an NSNumber that wraps around a value of type Int8 also has a type encoding of ‘c’. Therefore, a user who passes in a value of 0 or 1 (of type Int8) into JSON will expect to see the numbers 0 or 1 as the output because that was the intent. Unfortunately, that value will be wrapped into NSNumber and be considered a bool, so the user will see ‘true’ or ‘false’ instead.
  Fix typo in README.md
  Turn on render documentation mode.
  Finish subscript part. Add descriptions.
  Add getting a string using a path to the element.
