Experimental iterator wrapper that is conditionally parallel or serial, using
Rayon's `ParallelIterator` or the standard `Iterator` respectively.

## Usage

First add this crate to your `Cargo.toml`:

```toml
[dependencies]
rayon-cond = "0.4"
```

Then in your code, it may be used something like this:

```rust
use rayon_cond::CondIterator;

fn main() {
    let args: Vec<_> = std::env::args().collect();

// Run in parallel if there are an even number of args
    let par = args.len() % 2 == 0;

CondIterator::new(args, par).enumerate().for_each(|(i, arg)| {
        println!("arg {}: {:?}", i, arg);
    });
}
```

`rayon-cond` currently requires `rustc 1.63.0` or greater.
