Add AMM functionality: - InstanceCreate - Deposit - Withdraw - Governance - Auctioning - payment engine integration To support this functionality, add: - New RPC method, `amm_info`, to fetch pool and LPT balances - AMM Root Account - trust line for each IOU AMM token - trust line to track Liquidity Provider Tokens (LPT) - `ltAMM` object The `ltAMM` object tracks: - fee votes - auction slot bids - AMM tokens pair - total outstanding tokens balance - `AMMID` to AMM `RootAccountID` mapping Add new classes to facilitate AMM integration into the payment engine. `BookStep` uses these classes to infer if AMM liquidity can be consumed. The AMM formula implementation uses the new Number class added in #4192. IOUAmount and STAmount use Number arithmetic. Add AMM unit tests for all features. AMM requires the following amendments: - featureAMM - fixUniversalNumber - featureFlowCross Notes: - Current trading fee threshold is 1% - AMM currency is generated by: 0x03 + 152 bits of sha256{cur1, cur2} - Current max AMM Offers is 30 --------- Co-authored-by: Howard Hinnant <howard.hinnant@gmail.com>
