Note that it is the responsibility of the caller to ensure that all GPv2 invariants are upheld for the input settlement, otherwise this call will revert. Namely: - The fee factor cannot lead to fees > 0.1% - All orders are valid and signed - Accounts have sufficient balance and approval. - Settlement contract has sufficient balance to execute trades. Note   this implies that the accumulated fees held in the contract can also   be used for settlement. This is OK since:   - Solvers need to be authorized   - Misbehaving solvers will be slashed for abusing accumulated fees for     settlement   - Critically, user orders are entirely protected Note that settlements can specify fees encoded as a fee factor.  The fee factor to use for the trade. The actual fee is computed as `1 / feeFactor`. This means that the received amount is expected to be `executedBuyAmount * (feeFactor - 1) / feeFactor`. Note that a value of `0` is reserved to mean no fees. This is useful for example when settling directly with Uniswap where we don't want users to incur additional fees. Note that some parameters are encoded as packed bytes in order to save calldata gas.
