exchanges/futures: Implement open interest (#1417)

* adds open interest to exchanges * ADDS TESTING YEAH * New endpoints, BTSE, RPCS, cached * slight design change, begin gateio You will need to get cached for each exchange that supports it * gateio, huobi, rpc * fix up kraken, cache retrieval * okx, gateio * finalising all implementations and tests * definitely my final ever commit on this * Well, well, well * final v2 * quick fix of bug * test coverage, assert notempty, test helper Added a new testhelper for currency management because its very annoying in a parallel test setting which wastes so much space otherwise * minimises REST requests for Open Interest * types.Number merge misses * Minimises Kraken REST calls * len change, value -> pointer receiver * further fixup * fixes gateio, batch calculates open interest * single gateio, lint const fixes * rejig and more thorough oi for huobi * formatting expansion * minor fix for handling expiring contracts * rm unused Binance strings * add bybit support, fix bybit issues * oopsie doopsie, dont look at my whoopsie * Fix issue, remove feature * move an irrelevant function for the pr * mini bybit upgrades * fixes cli request bug
