Changes in version 0.1.1                        

  - x86_64 SIMD code is now enabled with compiler pragmas instead of -m
    flags (as ARM already was), so the build no longer uses non-portable
    compiler flags.

                        Changes in version 0.1.0                        

  - Initial implementation: crc32(), crc32c(), crc64nvme() and their
    _file() variants, backed by vendored aws-checksums v1.0.1 and
    aws-c-common v1.0.3.
