We didn't experience the expected performance improvements. Locally under
unit test there was aboout an order of magnitude throughput increase, but
when run against the history benchmark, this new approach was 60% slower.
We're reverting this for now to perform further analysis and better
understand the performance profiling of the python history stack.
- removed IAlgorithm dependency from time in force handlers
- renamed GoodTilCancelled to GoodTilCanceled
- added GTC time in force in regression algorithms
- inlined initialization of time in force handler dictionary
