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