Transition to stable Rust version

[crumblingstatue]

It's much easier to get packaged in distributions, etc, if we use a stable Rust version.
This is a long term goal, for now nightly features are considered useful for speeding up development.

Hello, if you are intrested I wanted to help to rewrite the try_blocks to stable Rust.
To make the smallest changes possible my idea was to translate try_blocks to closures to keep the ease of use of the ? operator.

An example would be to rewrite a try_block from this: (from app.rs):

let result: anyhow::Result<()> = try {
    let amount = src_clone.read(&mut buf)?;
    buf.truncate(amount);
    tx.send(buf)?;
};

To something like this:

let result = || -> anyhow::Result<()> {
    let amount = src_clone.read(&mut buf)?;
    buf.truncate(amount);
    tx.send(buf)?;
    Ok(())
}();

If you are interested let me know.

Thank you, this is something to consider, but for now hexerator depends on a lot of different nightly features, so it's not high priority to stop using them.
Ideally, when the time comes to start using stable Rust, try blocks will be a stable feature.
Although that might be too optimistic of an assumption.

Thank you for your suggestion though!

No problem, if there is something else I can help with let me know!
