FutureExt::timeout panics on Duration::MAX

[jocutajar]

Ahoj!

This:

async_std::future::pending::<()>()
        .timeout(Duration::MAX)
        .await?;

Panics:

thread 'main' panicked at 'overflow when adding duration to instant', library/std/src/time.rs:374:33

Proposal: use some form of saturating or checked add.

Many thanks, Yo

I'm worried that Async_STD doesn't commit code anymore
