This commit refactors the way series are represented and handled within the AST. Key changes include: - Introducing `SeriesStorage` and `PushableStorage` traits to provide a more unified and type-safe interface for series data. - Renaming `Object` trait and its methods to clarify that it's for RTL extensions other than series (like Streams). - Updating the `Value` enum to have a distinct `Series` variant, separating it from `Object`. - Adjusting various parts of the `VM` and `register` functions to work with the new series traits and `Value::Series` variant. This change aims to improve the type system's clarity and safety when dealing with series data, aligning with Rust's best practices for trait design.
