Design default API for icon package

[bartaxyz]

This package will be used even by packages scoped inside of this one. Therefore it should have nice and expandable API. This issue will cover how will it look.

import XYZIconSet from 'xyz-icon-set';

/*
 *  [ iconName: string ]: Icon
 *  returns all icon names in dash-case format
 */

const paperPlane = XYZIconSet.PaperPlane;
paperPlane.name === 'paper-plane';
paperPlane.source === '<svg wid...';

Import just specific icon

import { PaperPlane } from 'xyz-icon-set';

/*
 *  Icon object
 *  {
 *    name: string,
 *    source: string,
 *  }
 */

PaperPlane.name === 'paper-plane';
PaperPlane.source === '<svg width="24" height="24"><path style="fill:#000" ...';
