This prevents the need for constructing a VideoReformatter for cases where frame.to_ndarray() is called without arguments:

import av
import numpy as np
frame = av.VideoFrame(1920, 1080, format="rgb24")
%timeit frame.to_ndarray()

Before:

1.75 μs ± 10.4 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each)

After:

1.39 μs ± 2.76 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each)

Only call reformat if necessary
