At the moment, our skip indexes record min/max ordinal/value per range of doc IDs. It would be natural to extend it to other pre-aggregated data such as a sum and value count, which facets could take advantage of. This change switches `docValuesSkipIndex` from a boolean to an enum so that we could release such changes in the future in an additive fashion, by adding constants to this enum and new methods to `DocValuesSkipper`.

Building
Basic steps:
- Install OpenJDK 21.
- Clone Lucene's git repository (or download the source distribution).
- Run gradle launcher script (
gradlew).
We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.
