Review comment:
Doing more research, I don't think it's possible to detect if norms are
disabled upfront: `LeafReader#getNormsValues` could be `null` if a field uses
norms but happens to be missing from a segment. I opted to just document this
requirement (as we do for the fact norms must be additive and encoded in a
certain way). If the calling application has its own notion of schema, it can
enforce the norms requirements upfront.
