pypi version is inconsistent

In trying to track down the status of issue #268, I discovered that the current pypi version is listed as 2.13.0, but the `__init__.py ` file still lists the version as 2.12.1. Not sure which is the canonical version number. Incidently, the indent issue mentioned in #268 does not appear fixed in the current pypi version. From pypi version supposedly 2.13.0 `__init__.py ` : ``` """Powerful and Lightweight Python Tree Data Structure.""" __version__ = "2.12.1" __author__ = "c0fec0de" __author_email__ = "c0fec0de@gmail.com" __description__ = """Powerful and Lightweight Python Tree Data Structure.""" __url__ = "https://github.com/c0fec0de/anytree" ```
