VolodymyrBg opened PR #12618 from VolodymyrBg:fix/onnx-optimize-byte-conversion to bytecodealliance:main:

The functions created unnecessary intermediate Vec allocations - f32_vec_to_bytes allocated a Vec<[u8; 4]> then flattened it, and bytes_to_f32_vec had triple allocation with double collect.
Replaced with single-pass flat_map and simplified map with single collect, matching the pattern already used in winml.rs.
