The functions created unnecessary intermediate Vec allocations -
f32_vec_to_bytesallocated aVec<[u8; 4]>then flattened it, andbytes_to_f32_vechad triple allocation with double collect.Replaced with single-pass
flat_mapand simplifiedmapwith singlecollect, matching the pattern already used in winml.rs.
