Fixes a bug where we were using the security's data resolution to compute the insight's close time. This led a case such as insight.Period == 20days to step 20days worth of tradable minutes (assuming minute data resolution), yielding a close time that was very far in the future. We also add different means of specifying an insight's period/close time: 1. Specify insight period as a TimeSpan and we compute close time 2. Specify insight period and a resolution and bar count and we compute close time 3. Specify insight close time local directly and we compute the insight period The key here is maintaining consistency between the three different approaches which is heavily validated with the corresponding unit tests. Edits also made to trust the insight's close time as the analysis end time in the case where the analysis period == insight period (extra analysis period = 0). Given the current setup (extra analysis period == 0), this guarantees that close and analysis end times are equivalent. Regression statistics were updated and expectedly we get many more insights that have completed analysis, and as such, average scores have also changed.
