Trait noble_authorship::FilterUncle

pub trait FilterUncle<Header, Author> {
    type Accumulator: Default;
    fn filter_uncle(
        header: &Header, 
        acc: &mut Self::Accumulator
    ) -> Result<Option<Author>, &'static str>;
}

Additional filtering on uncles that pass preliminary ancestry checks.

This should do work such as checking seals
