FetusShiba.addLiquidity(uint256,uint256) (#754-767) sends eth to arbitrary user
Dangerous calls:
- V2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#759-766)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

FetusShiba._transfer(address,address,uint256) (#666-701) uses a dangerous strict equality:
- CoolDown[to] == 0 (#677)
FetusShiba._transfer(address,address,uint256) (#666-701) uses a dangerous strict equality:
- (block.number.sub(CoolDown[from]) < 2) || (block.number.sub(CoolDown[from]) == 100) (#684)
Don't use strict equality to determine if an account has enough Ether or tokens.
