Jpstat

Fix the DataFrame cleaning bug in `core.get_data` when setting `lang="E"`.
Add to README the method of circumvent any problem of `Note` by using `return_note=False`.

This release adds string normalization for all `estat` functions.

This is the second bug-fix release for 0.0.3.

- Add the information of API_id for the result of `estatFile.get_list`
- Fix the `estat.get_data` when data note returned is a dictionary

This is a minor bug-fix release for 0.0.3. Available functions for both estat api and estat files now work correctly.

The release will be available via PyPI:

python
pip install --upgrade jpstat


If above code fails to upgrade to 0.0.3.1 version, you can try `pip uninstall jpstat` and then `pip install jpstat` again.
