TED [Teddi] Token

Teddi.swapBack() (contracts/Teddi.sol#896-926) sends eth to arbitrary user
Dangerous calls:
- (success) = address(tedRiskFreeValueReceiver).call{gas: 30000,value: amountETHToTreasuryAndRFV}() (contracts/Teddi.sol#922-925)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
