Fjord Token Staking

When authorizedSablierSenders calls cancel, be sure to have enough gas. Otherwise, if the onStreamCanceled function reverts due to lack of gas, the funds in the NFT will continue to be pledged.

claimReceipts[msg.sender].requestEpoch > 0 already contains claimReceipts[msg.sender].requestEpoch >= currentEpoch - 1.

It is necessary to ensure that the points and staking contracts are deployed at the same time, otherwise the time difference may cause an attacker to pledge and obtain points in the same staking cycle and then cancel the pledge. And there are different cycles in Points. This shortens the time to obtain points.
