These bounds should now be applied to GroupEncoding::Repr and UncompressedEncoding::Repr. Also add use core::hash::Hash at the top of the file instead of the explicit form here.

This change would now apply to Curve::batch_normalize, and would look something like:
use core::borrow::{Borrow, BorrowMut};
...
fn batch_normalize<P: Borrow<Self>, Q: BorrowMut<Self::AffineRepr>>(p: &[P], q: &mut [Q]) {However, when I tried this locally, I ran into issues with &P not implementing Curve, that I wasn't immediately able to figure out how to resolve. Perhaps the P: Borrow<Self> is unnecessary flexibility?

Adds some basic functions to encoded points and makes batch_normalization slightly easier to use
