Supports CRC-32/ISO-HDLC (aka “crc32”) via FFI using the crc32fast Rust library for a >10X performance increase over PHP’s native crc32() implementation.

The Problem
We'd like to use CRC-32/ISO-HDLC (aka 'crc32') at SIMD-accelerated rates, too, not just CRC-64/NVME](https://reveng.sourceforge.io/crc-catalogue/all.htm#crc.cat.crc-64-nvme).
The Solution
Leverage the crc32fast-lib C-compatible shared Rust library to accelerate CRC32 computation >10X.
Changes
CRC-32/ISO-HDLCsupport.
