Enhanced this lib with CLI arguments to specify pipe names, directive names, service name and methods.

[EnilPajic]

Now it is possible to use command-line arguments to specify

• (multiple) pipe names (--pipe translate --pipe myTranslate),
• (multiple) directive names (--directive translate --directive myTranslate),
• service name (--service-name MyTranslateService)
• service methods (default were get, instant and stream): --service-method-name get --service-method-name myCustomGet
• marker name (-m i18n), basically incorporated https://github.com/biesbjerg/ngx-translate-extract/pull/229/ by @pieterhendrickx

@biesbjerg @EnilPajic this is a very useful feature. When do you think you will merge this?
