MAJOR ADDITIONS

• Introducing EventsToTimeRange Derived Tables : EventsToTimeRange is a derived table implementation in PhenEx that converts discrete event dates into continuous time periods. It's particularly valuable for medication adherence and discontinuation studies where you only have prescription dates without explicit durations.
• R bindings for Phenex : This PR enables R users to call Phenex from within their R environment providing a more seamless experience for R users in hybrid workflows.
• Introducing Stackable Regimens! : Often we want to see how drugs are utilized; are people taking a single drug, a combination, and if so, which ones? Now you can use StackableRegimens to answer exactly this question. Given a list of input phenotypes, It generates a list of phenotypes computing all possible combinations of those inputs.
• Diagnostic plots : Added some interactive plots good for sanity checking your analysis and interpreting the results
