SHR [shera] Token

shera.swapAndLiquify(uint256) (#2117-2155) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(marketingAmount) (#2142)
- developmentAndDonationWallet.transfer(buybackAmount) (#2145)
shera.addLiquidity(uint256,uint256) (#2189-2201) sends eth to arbitrary user
Dangerous calls:
