SACA [Saitama Cat] Token

SaitamaCat.rescueTokenFromContract(bool,address,uint256,address) (contracts/SaitamaCat.sol#159-172) ignores return value by IERC20(tokenAddress).transfer(receiver,amount) (contracts/SaitamaCat.sol#170)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

SaitamaCat.manualSetup(uint8,uint8) (contracts/SaitamaCat.sol#304-319) contains a tautology or contradiction:
- require(bool,string)(percentSwapLimit_ >= 0 && percentSwapLimit_ <= swapLimitDenominator_,Error: out of range!) (contracts/SaitamaCat.sol#309-313)
Fix the incorrect comparison by changing the value type or the comparison.

SaitamaCat.manualSetup(uint8,uint8) (contracts/SaitamaCat.sol#304-319) should emit an event for:
- _swapLimit = totalSupply().mul(percentSwapLimit_).div(swapLimitDenominator_) (contracts/SaitamaCat.sol#314-316)
Emit an event for critical parameter changes.

SaitamaCat.rescueTokenFromContract(bool,address,uint256,address).receiver (contracts/SaitamaCat.sol#163) lacks a zero-check on :
- address(receiver).transfer(contractETHBalance) (contracts/SaitamaCat.sol#168)
Check that the address is not zero.
