Helpers for moving Statistics across the FFI boundary as prost-encoded
datafusion_proto_common::Statistics bytes.
Statistics contains Precision<ScalarValue> for column min/max/sum,
and ScalarValue is a large enum that’s impractical to mirror in
#[repr(C)]. The proto round-trip already exists in datafusion-proto-common
and is the same pattern used to ship filter expressions across the FFI
boundary, so we reuse it here.
