Update Icons

[hectorAguero]

So currently I'm using MaterialCommunityIcons and FontAwesome5 from other flutter packages and I would like to use only one dependency for both, but the Icons that i'm using are from the new versions.

I let a list about the outdated icon sets

• AntDesign to the last one
• Feather v4.7.0 to v4.28.0
• FontAwesome 5 v5.7.0 to v5.13
• Ionicons v4.2.4 to v5.0.0
• MaterialCommunityIcons v4.0.96 to v5.1.45.
• Octicons v8.0.0 to v9.6.0

Some updated icon sets remove some icons like Ionicons

react-native-vector-icons repo have PR(not merged) for FontAwesome and MaterialCommunityIcons v5.0.45, but they haven't released a new version in over a year

*Octicons: v10.0.0 (Octicons-v2)

Hello everybody!
Since the libraries here haven't been updated for a long time, I have done this now briefly.
So instead of 3k icons you can now use over 15k icons.
I couldn't update octicons to the last available version because the codepoints are missing.

@ThinkBIG-Company any plan to migrate to null safety?

Hello, I'm having some problem with the last release, some getters are broken:

                                                 
 Error: Getter not found: 'ios_heart_outline'.
              iconData: Ionicons.ios_heart_outline,

Also all the FlutterIcons._faw now are FlutterIcons._fa I don't know if this change is intentional.

I pushed out a fork which includes all missing icons including Fontisto fonts and jibiel's fixes for null safety support: https://pub.dev/packages/flutter_font_icons
