Add support for extract words from vars, example:

[EndyKaufman]

export class Form {
  static titles: any = {
    id: 'Id',//translate
    name: 'Name'//translate
  };
  id: number;
  name: string;
}

Thank you for the PR and sorry for getting back to you so late.

I'm going to implement this feature in a future version, but in a different way, using a dummy/noop marker function:

import { __ } from '@biesbjerg/ngx-translate-extract';

__('String to be extracted with {{value}}', { value: 'dynamic value' });

Or aliased

import { __ as markerFn } from '@biesbjerg/ngx-translate-extract';

markerFn('String to be extracted with {{value}}', { value: 'dynamic value' });

And using an argument when extracting --marker-function markerFn (defaults to __) for example.

Something along those lines :-)
