The `series` constructor now only accepts the `lookback` limit. The element type is inferred by the type checker and implicitly added as a schema argument during compilation. This simplifies the API and centralizes type inference. This change also includes: - Updates to example scripts (`HMA.myc`, `sma.myc`, `soa_series.myc`) to reflect the new `series` signature. - Modifications to the `TypeChecker` to handle the inferred schema injection. - An addition of a regression test for type inference through nested closures with `series`. - Removal of `#[allow(dead_code)]` from several `TypeChecker` methods as they are now used. - Update to `rtl/prelude.myc` macro `cache`. - Update to `rtl/series/mod.rs` to reflect new signature. - Update to `ast/types.rs` to allow `series` to be indexed with an integer to retrieve its element type.
