* surprise train commit

* basic distinctions

* the terms of binance are confusing

* renames and introduction of allocatedMargin

* add new margin funcs

* pulling out wires

* implement proper getposition stuff

* bad coding day

* investigate order manager next

* a broken mess, but a progressing one

* finally completes some usdtmargined stuff

* coinMfutures eludes me

* expand to okx

* imports fix

* completes okx wrapper implementations

* cleans and polishes before rpc implementations

* rpc setup, order manager features, exch features

* more rpc, collateral and margin things

* mini test

* looking at rpc response, expansion of features

* reorganising before the storm

* changing how futures requests work

* cleanup and tests of cli usage

* remove silly client side logic

* cleanup

* collateral package, typo fix, margin err, rpc derive

* uses convert.StringToFloat ONLY ON STRUCTS FROM THIS PR

* fix binance order history bug

* niteroos

* adds new funcs to exchange standards testing

* more post merge fixes

* fix binance

* replace simepletimeformat

* fix for merge

* merge fixes

* micro fixes

* order side now required for leverage

* fix up the rest

* global -> portfolio collateral

* Update exchanges/collateral/collateral_test.go
