Implement the siring feature where a kitty can be offered for breeding in the marketplace so someone else can create a new kitty with them.
- Add
mapping(uint256 => address) sireAllowedToAddress- Tracks approval for siring
- Should only be set by the owner or an approved operator (i.e. the Marketplace)
- Add new type of offer in the Marketplace for siring
