What Does This Do

Updates V0.4 serializer to use TagMap.EntryReader API to avoid boxing primitives

Motivation

Reduce allocation -> reduces garbage collection -> improves throughput predictability

Additional Notes

Builds on EntryReader API changes

Refining handling of primitive types

Fixed bug TagValueConversions.toBoolean
Could cause LegacyTagMap.EntryReader to produce incorrect answers to some queries

For simplicity, now treating Byte and Short as Integer.  That will make calling code doing primitive handling simpler.

By any chance do you have jmh tests ?
