Helper to make a `TinyVec`.

You specify the backing array type, and optionally give all the elements you want to initially place into the array.

    use tinyvec::*;

    // The backing array type can be specified in the macro call
    let empty_tv = tiny_vec!([u8; 16]);
    let some_ints = tiny_vec!([i32; 4] => 1, 2, 3);
    let many_ints = tiny_vec!([i32; 4] => 1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

    // Or left to inference
    let empty_tv: TinyVec<[u8; 16]> = tiny_vec!();
    let some_ints: TinyVec<[i32; 4]> = tiny_vec!(1, 2, 3);
    let many_ints: TinyVec<[i32; 4]> = tiny_vec!(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
