  1. keccak: add asm feature; use cpufeatures on aarch64

    Gates `asm` support under a crate feature.
    
    Uses the `cpufeatures` crate to detect the presence of the `sha3`
    extension for ARMv8 CPUs, automatically falling back to a software
    implementation if it isn't available.

  1. keccak: expose f1600_asm in public API

    When the `asm` feature is enabled on `aarch64` targets, exposes
    `f1600_asm` that relies on ARMv8 `sha3` hardware intrinsics.
