Reengineering the library to directly produce Go values instead of lexing and parsing beforehand

[xnacly]

This pr implements at least a better lexing approach and at most will combine lexing and parsing into a single in memory go value producer. Reducing the need for tokens and replacing the recursive descent parser with a dfa->go values system, hopefully this will outperform encoding/json by even more that the current 2.5-4x.

// converts any valid JSON to go values, result may be:
//
//	T = map[string]T, []T, string, float64, true, false, nil
//
// deserialize merges the concepts of lexical analysis with semantic and
// syntactical analysis, while producing direct go values out of the
// aforementioned. This results in a large performance improvements over the
// traditional approach, since the deserialisation process no longer requires
// multiple passes and intermediate values.
//
// At a high level this works by representing JSON as a table of states and
// possible input characters determining the follow state (table driven DFA).
// This makes deserialisation of large JSON inputs very fast.
