Rust implementation of the CRC-32-Castagnoli algorithm.
Provides support for an optimized software implementation and a hardware-accelerated (SSE 4.2) one.
If you have SSE 4.2 enabled at compile time, it will only build the SSE implementation.
Otherwise, it will build both versions, and use cpuid to choose the best implementation at run time.
The code is inspired by Mark Adler's CRC32C implementation.
