Array arguments

Without jlrs we had to convert arrays to a pointer to their first element if we wanted to access them in a ccalled function, with jlrs taking an array argument directly isn't an issue.

Any of the aliases of ArrayBase can be used as an argument type, they enforce the obvious restrictions: Array only enforces that the argument is an array, TypedArray puts restrictions on the element type, RankedArray on the rank, and TypedRankedArray on both. Other aliases like Vector are expressed in terms of these aliases so they can also be used as argument types.

use jlrs::prelude::*;

// Safety: the array must not be mutated from another thread
unsafe fn sum_array(array: TypedArray<f64>) -> f64 {
    array.bits_data().as_slice().iter().sum()
}

julia_module! {
    become julia_module_tutorial_init_fn;

    fn sum_array(array: TypedArray<f64>) -> f64;
}

julia> module JuliaModuleTutorial ... end
