PKCS#7Viewer Updated to 64-bit binary

Refreshed the binaries for PKCS#7Viewer for 64-bit operating systems including all versions of Mac OS X and macOS from 10.8 Mountain Lion to 10.15 Catalina.

Assuming it makes it to the Mac App Store, you can find it there; otherwise, there is a free version available for download from this website.

The question is: "Am I feeling motivated enough to try getting PCKS#7Viewer into the Mac App Store?" Certainly the codesigning procedure has been streamlined in Xcode.

PKCS7Viewer has been notarized for easier access on Catalina - however - some features still are not available; I am continuing to research this issue.
