refactor!: make Position generic over offset type
Previously Span was generic over R just so that it could provide the method: fn from_reader(reader: &R) -> Self; and properly implementing that method again relied on R implementing the Position trait: impl<P: Position> Span<P> for Range<usize> { .. } which was a very roundabout and awkward way of doing things. It makes much more sense to make the Position trait generic over the return type of its method (which previously always had to be usize). Which lets us provide a blanket implementation: impl<R: Reader> Position<NoopOffset> for R { .. }
