Description: Adds target constructors that make it easy to use Python, Julia, and
    Rust inside a 'targets' pipeline using 'reticulate', 'JuliaCall', and 'rextendr'.
    Provides tar_target_py(), tar_target_jl(), and tar_target_rs() (with matching
    _raw() variants), each mirroring 'targets::tar_target()' and
    'targets::tar_target_raw()'. Python and Julia steps run a script via a live
    interpreter with optional R pre- and post-scripts; Rust steps compile
    '#[extendr]' functions and call them from an R post-script. Results are
    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(), and a Rust toolchain with Cargo for
        tar_target_rs() (on Windows, the GNU toolchain, to match R's
        ABI). A pipeline that uses a single language needs only that
        language's toolchain, and a pipeline that uses none of these
        constructors needs no external toolchain at all.
