pangu.js -- Paranoid text spacing for good readability, to automatically insert whitespace between CJK and half-width characters (alphabetical letters, numerical digits and symbols).

positional arguments:
  text_or_path   the text or file path to apply spacing; omit it to read stdin when input is piped

optional arguments:
  -h, --help     show this help message and exit
  -v, --version  show program's version number and exit
  -t, --text     specify the input value is a text
  -f, --file     specify the input value is a file path (pass - to read from stdin)
  -c, --check    check if text has proper spacing (exit 0 if yes, 1 if no)
