debug mode (-d option) does not work in the python version

[Nishihara-Daiki]

A help describes that -d option "print the bebug information":

$ sudachipy tokenize -h
usage: sudachipy tokenize [-h] [-r file] [-m {A,B,C}] [-o file] [-s string] [-a] [-d] [-v] [file ...]

Tokenize Text

positional arguments:
  file           text written in utf-8

options:
  -h, --help     show this help message and exit
  -r file        the setting file in JSON format
  -m {A,B,C}     the mode of splitting
  -o file        the output file
  -s string      sudachidict type
  -a             print all of the fields
  -d             print the debug information
  -v, --version  print sudachipy version

but, it doesn't actually work:

$ echo '外国人参政権' | sudachipy
外国人参政権    名詞,普通名詞,一般,*,*,*        外国人参政権
EOS
$ echo '外国人参政権' | sudachipy -d
外国人参政権    名詞,普通名詞,一般,*,*,*        外国人参政権
EOS

-d option is not implemented for the python version now (#207).
maybe we should raise warnings on its use.
