TAS Client for Experimentation Services

The `tas-client` package, currently at version 0.3.2, provides a client-side library for querying, refetching, and caching data from an experimentation service endpoint. It is specifically designed to interact with endpoints whose results conform to a required experimentation data structure. This client library emphasizes integration via consumer-provided implementations of key interfaces, including `IExperimentationFilterProvider`, `IExperimentationTelemetry`, and `IKeyValueStorage`, allowing for flexible integration with various application environments. Its focus on managing experiment data, including features like configurable refetch intervals and treatment variable retrieval, differentiates it from generic HTTP clients by providing specialized logic for experimentation workflows. Given its `0.x` version, releases are likely feature-driven and ad-hoc rather than on a fixed schedule, indicating an active but evolving development phase.
