Review Comment:
I think the reason for leaving out the field in `BuildAvroProjection` was to
make this check work. But I'm pretty sure that the Avro Schema needs to match
the Iceberg Schema. So this will probably need to have some other way of
detecting that the field will not be read from the field because it was missing
from the file schema.
