Additional encoding/decoding optimization

* Replace reader/writer interfaces with concrete `buffer` type.
* Avoid intermediate buffer during map encoding.
* Avoid `milliseconds` marshal allocation.
* Remove `errNull`/`isNull` from marshal and avoid defer in hot path.
* Cleanup of decoding code.
* Minimize bounds checks by adding hints.
* Check interface types last in type switches.
* Add fastpath in unmarshal for `**uint32`.
