[Open Assets] Hug Support for Vanilla Chars Beta-V1.2

After a long while, fang now has the ability to hug other players.

The sprite was done about 4 months ago. Reason for not releasing once it was done was due to the upcoming character resprites. As for now, we finally agreed to release the update and kept it as beta until we make newer sprite for the upcoming new ones.

- Fang now has the ability to hug.

Changes/Additions
- Metal Sonic now has the ability to hug.
- Fixed Hug sound when hugging someone back.
