  1. Optimize hex_encode() and hex_decode() using SIMD. 

    This commit adds new implementations of hex_encode() and
hex_decode() that use routines (both existing and new) from simd.h.
Testing indicates these new implementations are much faster for
larger inputs.  For smaller inputs and for hex_decode() inputs
containing bytes outside of [0-9A-Fa-f], we use the existing scalar
versions.  Since we are using simd.h routines, these optimizations
apply to both x86-64 and AArch64.
