kakasi command line -v option no longer works.

[denny-vandenberg]

Describe the bug Command line kakasi replacement doesn't support -v command line option. This same issue breaks the -h option as well.

To Reproduce Steps to reproduce the behavior: (example)

1. Prepare test data attached as 'file' in current directory.
2. Run following code with python3.

$ pip3 install pykakasi

Does #109 work for you?

$ kakasi -v
pykakasi v2.0.2.dev13 on Python 3.8.5 [CPython GCC 9.3.0]

[denny-vandenberg]

So, #109 doesn't seem to work with python 3.7. For python 3.7, metadata doesn't appear to exist inside importlib. If I install pip3 install importlib-metadata and use the behavior from https://github.com/miurahr/pykakasi/commit/f1a2d16e1acec80f3771d285bf90d4394719792b specifically the following: try: from importlib import metadata as importlib_metadata # noqa except ImportError: import importlib_metadata

after that modification it appears to work.

[miurahr]

Thank you for feedback. v2.0.4 is out with suggested modifications.

[denny-vandenberg]

It works perfectly, thanks!
