Update libprio-rs dependency to version 0.8.0. (#256)

This version of libprio-rs implements draft-irtf-cfrg-vdaf-01, which is the version we are targeting for interop tests. This change is large but mostly-mechanical. A large number of line changes are due to the new `L` const generic parameter to the VDAF Aggregator trait. This parameter is effectively the underlying PRG's seed size. Unfortunately, Rust currently doesn't allow const generic parameters to be inferred; there is an open issue to resolve this, but it doesn't appear to have received much attention thus far[1].
