1. To prevent loops external manipulation, limit the number of bids that can be created.
2. Enhance the reentrancy guard in closeExpiredOffer and cancelOffer in MarsbaseExchange. Add MarsBaseExchangeAttackMock and security test
3. Validate _nextOfferId in setNextOfferId to ensure that the nextOfferId won't overwrite the current active offer.
4. Introduce maximumFee and perform safe-range validation for feeAlice and feeBob. Make SCALE a constant.
5. Add receive() external payable {} to make MarsbaseExchange and MarsbaseBestBid being able to receive ETH
6. Use fixed pragma version 0.8.19 which is the latest version
7. Use prettier and solhint to format the code. Format .sol files: yarn prettier-sol, .js files: yarn prettier-js
