FacetSetDecoder (Lucene 9.4.0 facet API)

```
public interface FacetSetDecoder
```
A functional interface for decoding facet set values into comparable `long` ones. You can use it by e.g. implementing a static method with the same signature and then pass it as YourClass::decode.

WARNING: This API is experimental and might change in incompatible ways in the next release.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`decode(BytesRef bytesRef, int start, long[] dest)`	Decodes the facet set dimension values into the given destination buffer and returns the number of bytes read.
`static int`	`decodeInts(BytesRef bytesRef, int start, long[] dest)`	An implementation of `decode(BytesRef, int, long[])` for int/float dimension values which were encoded with `IntFacetSet` and `FloatFacetSet` respectively.
`static int`	`decodeLongs(BytesRef bytesRef, int start, long[] dest)`	An implementation of `decode(BytesRef, int, long[])` for long/double dimension values which were encoded with `LongFacetSet` and `DoubleFacetSet` respectively.
