Support USD-M futes live feeds and exchange info
Add the usd-futes "Pair" type and thus ability to load all exchange (info for) contracts settled in USDT. Luckily we don't seem to have to modify anything in the `Client` interface (yet) other then a new `.mkt_mode: str` which determines which endpoint set to make requests. Obviously data received from endpoints will likely need diff handling as per below. Deats: - add a bunch more API and WSS top level domains to `.api` with comments - start a `.binance.schemas` module to house the structs for loading different `Pair` subtypes depending on target market: `SpotPair`, `FutesPair`, .. etc. and implement required `MktPair` fields on the new futes type for compatibility with the clearing layer. - add `Client.mkt_mode: str` and a method lookup for endpoint parent paths depending on market via `.mkt_req: dict` Also related to live feeds, - drop `Struct` typecasting instead opting for specific fields both for speed and simplicity atm. - breakout `subscribe()` into module level acm from being embedded closure. - for now swap over the ws feed to be strictly the futes ep (while testing) and set the `.mkt_mode = 'usd_futes'`. - hack in `Client._pairs` to only load `FutesPair`s until we figure out whether we want separate `Client` instances per market or not..basic_buy_bot
