Description

Example from Python, showing that you can currently create a ChunkedArray with incompatible types:

In [8]: a1 = pa.array([1, 2])

In [9]: a2 = pa.array(['a', 'b'])

In [10]: pa.chunked_array([a1, a2])
Out[10]:
<pyarrow.lib.ChunkedArray object at 0x7fca50704d20>
[
  [
    1,
    2
  ],
  [
    "a",
    "b"
  ]
]

So a ChunkedArray::Validate can be implemented (and which should probably be called by default upon creation?)
