fix opening of files provided with --config-path

[Rogdham]

Hello, when using --config-path option, ini.parse fails to parse the file as fs.readFileSync returns a Buffer and not a string.

/redacted/locize-cli/node_modules/ini/lib/ini.js:72
  const lines = str.split(/[\r\n]+/g)
                    ^

TypeError: str.split is not a function
    at Object.decode (/redacted/locize-cli/node_modules/ini/lib/ini.js:72:21)

Note that the above stacktrace is silenced by the try-catch, making it all the more confusing.
