np.fromstring's binary mode is deprecated and removed in NumPy 2.x. Coerce msgpack/legacy buffers to bytes and return writable copies so samples using string_to_uint8_array keep working on modern NumPy.

Summary
numpy.fromstringbinary mode is deprecated and removed in NumPy 2.x, which breaks AirSim’s public helpers used by samples (string_to_uint8_array/string_to_float_array).This switches those helpers to
np.frombufferwith a small bytes-like coerce path for msgpack/legacystrbuffers, returning writable copies (same practical behavior as the old helpers).Motivation
Users on modern NumPy could not decode packed image buffers through the supported helpers without warnings or failures.
