Description: Adds target constructors that make it easy to use
        'Python', 'Julia', 'Rust', and 'C++' inside a 'targets'
        pipeline using 'reticulate', 'JuliaCall', 'rextendr', and
        'Rcpp'. Provides tar_target_py(), tar_target_jl(),
        tar_target_rs(), and tar_target_cpp() (with matching _raw()
        variants), each mirroring 'targets' tar_target() and
        tar_target_raw() functions. 'Python' and 'Julia' steps run a
        script via a live interpreter with optional R pre- and
        post-scripts; 'Rust' and 'C++' steps compile functions and call
        them from an R post-script. Results are then returned either as
        converted R objects or as files written to disk (format =
        "file"). Dynamic branching, environment/version selection, a
        'crew' controller for isolation, and the full set of
        tar_target_raw() arguments are supported.

SystemRequirements: The external language toolchains are optional and
        each is only required by its matching targets constructor: a
        Python installation for tar_target_py(), a Julia installation
        for tar_target_jl(), a Rust toolchain with Cargo for
        tar_target_rs() (on Windows, the GNU toolchain, to match R's
        ABI), and a C++ compiler reachable by R (e.g. via Rtools on
        Windows) for tar_target_cpp(). A pipeline that uses a single
        language needs only that language's toolchain.
