nested block_on's deadlocks

[hymm]

I was trying to test smolscale with bevy, and there's some code that needs to bridge sync to async multiple times. Similar to the following:

let mut x = 0;
smolscale::block_on(async move {
    let task = smolscale::spawn(async move {
        smolscale::block_on(async move {
            let task = smolscale::spawn(async move {
                x += 1;
            });
            task.await;
        });
    });
    task.await;
});

but things end up deadlocking. I can also get a deadlock with just nesting the block_on's, but not sure if this is related.

let mut x = 0;
smolscale::block_on(async move {
    smolscale::block_on(async move {
        x += 1;
    });
});

I will look into this issue! This is something I've noticed as well.

This is fixed in the latest version.
