Provide icon mapping

[davidpanic]

Currently you have to specify your own map of key value pairs for all icons if you want to use a library that requires the icons to exist such as flutter_remote_icon. That could easily get desynchronized if the library updates.

If there was a Map<String, IconData> somewhere in the library you could simply do this and it would always be synchronized correctly with what the library provides:

//library code
const Map<String, IconData> communityMaterialIconsMap = {
  'ab_testing': CommunityMaterialIcons.ab_testing,
  'abjad_arabic': CommunityMaterialIcons.abjad_arabic,
  // The rest of the icons
}

// user code
XIcons.register(
  'community',
  {
    for (final iconName in communityMaterialIconsMap.keys) 'community://$iconName': communityMaterialIconsMap[iconName],
  },
);

Wow. Great. Another completely dead flutter package! If you stopped maintaining this, MARK IT AS DISCONTINUED ON PUB.DEV There is a reason that checkbox exists.
