SHA512 for CRC SHA context menu

That would save a lot of time for vcpkg maintainers because vcpkg uses SHA512 to verify checksums of downloaded files and the only out-of-the box solution on Windows is to use powershell.
Sadly, 7zip 24.08 can calculate only SHA1/SHA256.
Would be nice to have SHA512 support, too!
