ARROW-5286: [Python] support struct type in from_pandas https://issues.apache.org/jira/browse/ARROW-5286 We can infer struct type from dicts, but currently do not allow it in `from_pandas` because getting a "logical pandas type" is not implemented. I opted for now to let this return "object", as that is how pandas stores such data. Author: Joris Van den Bossche <jorisvandenbossche@gmail.com> Closes #4297 from jorisvandenbossche/ARROW-5286-from_pandas-structs and squashes the following commits: e803f9b4a <Joris Van den Bossche> ARROW-5286: support struct type in from_pandas
