* Added aarch64 optimized version of saber, lightsaber, and firesaber from pqclean * Updated to latest commit of pqclean which fixes saber aarch64. * Updated saber docs as per @dstebila's comment * Removed duplicate lines from README.md * Fixed local issue for duplicate lines in README.md. This is the output of the update docs script after fixing my local issue
