Examples

>>> decode_ternary_array((6,), b"\xb4\xe0")
array([ 1, -1,  1,  0, -1,  1])

>>> decode_ternary_array((2, 3), b"n\x80")
array([[ 0,  1, -1],
       [-1,  0,  0]])

>>> decode_ternary_array((2, 2, 3), b"K\xe48")
array([[[ 0,  1, -1],
        [-1,  1,  0]],

       [[ 1,  0,  0],
        [ 0, -1,  1]]])

>>> decode_ternary_array((2, 2, 3), b"K\xe5\x9c")
array([[[ 0,  1, -1],
        [-1,  1,  0]],

       [[ 1, -1,  0],
        [ 0, -1,  1]]])
