Updates to recode endpoint

The recode endpoint had changes which are reflected in #44

• siteRecode().version() was removed

• siteRecode().algorithms() returns all the supported algorithms and their versions

• siteRecode().siteGroup() was modified. It now takes 4 parameters. Note that behavior is not used for the seer algorithms and null can be passed in for that case.

NAACCR version in staging algorithm

Note that while this is version 5.0, it is still a minor release. The reason for the large version bump is that years ago a 4.x version was mistakenly released and cannot be removed from Maven Central. It was causing confusion so this version was raised to be the highest.

• Add support for new naaccr_version property in StagingVersion. Its purpose is to associate a staging algorithm version with a specific NAACCR release #32
• Various dependencies were also updated

Diagnostic confirmation

Added support for the new diagnostic confirmation field in the disease entity #30

Staging metadata changes

Support the upcoming changes to staging metadata. The metadata in StagingSchemaInput and StagingSchemaOutput changed from

public Set<String> getMetadata() {
        return _metadata;
    }

to

public List<StagingMetadata> getMetadata() {
        return _metadata;
    }

The new StagingMetadata class adds support for optional start and end years.

Minor fixes

Fixed MPH calls and updated staging output entity #29
