* include waiting functionality for depth change alert

* backtester: add word.

* log: include logger changes to impl with downstream integration

* engine: reduce params for loading exchange

* assort: rm verbose in tests, change wording in ob, expose sync.waitgroup for ext. sync options

* ticker: reduce map look ups and contention when using RW mutex when there are over 80% writes adds find last function to get the latest rate

* engine/syncmanager: add in waitgroup for step over for external package calls

* cleaup

* engine: linter fix

* currency/fx: include all references to fiat currencies to default

* orderbook: Add in fields to Unsafe type for strategies to detect potential out of sync book operations

* syncmanager: changed config variable to display correct time

* ordermanager: Add time when none provided

* currency/manager: update getasset param to get enabled assets for minor optimizations

* ftx: use get all wallet balances for a better accounts breakdown

* orderbook: unlock in reverse order

* bithumb: fixes bug on market buy and sell orders

* bithumb: fix bug for nonce is also time window sensitive

* bithumb: get orders add required parameter

* bithumb: Add asset type to account struct

* currency: improve log output when checking currency and it fails

* bithumb: Add error return on incomplete pair

* ticker:unexport all service related methods

* ticker/currency: fixes

* orderbook: fix comment
