Clone trait that is dyn-compatible

This crate provides a `DynClone` trait that can be used in trait objects, and a
`clone_box` function that can clone any sized or dynamically sized
implementation of `DynClone`. Types that implement the standard library's
[`std::clone::Clone`] trait are automatically usable by a `DynClone` trait
object.
[`std::clone::Clone`]: https://doc.rust-lang.org/std/clone/trait.Clone.html
The signature of `clone_box` is:
```rust
fn clone_box<T>(t: &T) -> Box<T>
where
T: ?Sized + DynClone
```
## Example
```rust
use dyn_clone::DynClone;
trait MyTrait: DynClone {
fn recite(&self);
}
impl MyTrait for String {
fn recite(&self) {
println!("{} ♫", self);
}
}
fn main() {
let line = "The slithy structs did gyre and gimble the namespace";
// Build a trait object holding a String.
// This requires String to implement MyTrait and std::clone::Clone.
let x: Box<dyn MyTrait> = Box::new(String::from(line));
x.recite();
// The type of x2 is a Box<dyn MyTrait> cloned from x.
let x2 = dyn_clone::clone_box(&*x);
x2.recite();
}
```
This crate includes a macro for generating the implementation `impl
std::clone::Clone for Box<dyn MyTrait>` in terms of `dyn_clone::clone_box`:
```rust
// As before.
trait MyTrait: DynClone {
/* ... */
}
dyn_clone::clone_trait_object!(MyTrait);
// Now data structures containing Box<dyn MyTrait> can derive Clone:
#[derive(Clone)]
struct Container {
trait_object: Box<dyn MyTrait>,
}
```
