> When working with arrow schemas it would be helpful to have a human readable 
> representation of the diff between two schemas.
> This could be either exposed as a function returning a string/diff object or 
> via a function raising an Exception with this information.
> For instance:
> {code}
> schema_diff = get_schema_diff(schema1, schema2)
> expected_diff = """
> - col_changed: int8
> + col_changed: double
> + col_additional: int8
> """
> assert schema_diff == expected_diff
> {code}
