Line 234 of tiingo.py needs to be updated according to new pandas update

[mo-atiff]

Current line : return pd.concat(dfs, self._concat_axis)
According to new pandas update it says we need to specify any Series or data-frame objects with the keyword 'objs' as a parameter
Update to : return pd.concat(objs=dfs, axis=self._concat_axis)
