fast JSON parser and validator for Go (library)

No custom structs, no code generation, no reflection.

Features:

 * Fast. As usual, up to 15x faster than the standard encoding/json.
 * Parses arbitrary JSON without schema, reflection, struct magic and code
   generation contrary to easyjson.
 * Provides a simple API.
 * Outperforms jsonparser and gjson when accessing multiple unrelated fields,
   since fastjson parses the input JSON only once.
 * Validates the parsed JSON unlike jsonparser and gjson.
 * May quickly extract a part of the original JSON with
   Value.Get(...).MarshalTo and modify it with Del and Set functions.
 * May parse array containing values with distinct types (aka non-homogenous
   types). For instance, fastjson easily parses the following JSON array
   [123, "foo", [456], {"k": "v"}, null].
 * fastjson preserves the original order of object items when calling
   Object.Visit.

Known limitations:

 * Requies extra care to work with - references to certain objects
   recursively returned by Parser must be released before the next call to
   Parse.  Otherwise the program may work improperly. The same applies to
   objects returned by Arena.
 * Cannot parse JSON from io.Reader.

Security:

 * fastjson shouldn't crash or panic when parsing input strings specially
   crafted by an attacker. It must return error on invalid input JSON.
 * fastjson requires up to sizeof(Value) * len(inputJSON) bytes of memory
   for parsing inputJSON string. Limit the maximum size of the inputJSON
   before parsing it in order to limit the maximum memory usage.
