In "basic usage example", call digest() instead of parse_at()

[DrTobe]

Hi, is it possible that in the basic usage example

#[interrupt]
fn TIM7() {
    let ingress = unsafe { INGRESS.as_mut().unwrap() };
    ingress.parse_at();
}

it should be

    ...
    ingress.digest();
    ...

instead?

It looks like you are absolutely right.

Guess that is the downside to having it marked as ignore in doc-tests.
If you find the time, a PR would be very welcomed :)
