Update and reintroduce `fractional-NFT`

[K1-R1]

The fractional-NFT application was temporarily archived awating the release of the Sway multi-token standard. Once this standard has been finalised and the version of forc that supports this standard is released; the fractional-NFT app should be updated and reintroduced.
