Fjord Token Staking

Functions with token transfer operations does not using `SafeTransferLib

All token transfer operations within `FjordStaking` contract already utilize SafeTransferLib. However, token transfer operations in `FjordAuction` contract functions like those in `bid`,`unbid`,`auctionEnd`,`claimTokens` and `AuctionFactory` contract function like `createAuction` still use the unsafe transfer method. Consider adjusting these transfer operations to also utilize SafeTransferLib.

Token which do not revert or return a boolean on failed transfer might fail silently, which will affect token accounting in contract

Manual Review

Consider using SafeTransferLib.safeTransfer() to handle such tokens. Just as used in token transfer operations within `FjordStaking`
