Description

(For completeness,) Luke should show KnnVector format information in the index browsing tab.

If the type of a field is a KnnVector,

• Show flag "K"
• Show its dimension
• Show its similarity function

More rich support for the codec - decoding or searching - could come later; I don't know if there are such use-cases.
