64bit support

[JanSimek]

Since you cannot run 32-bit applications on new silicon-based MacBooks, I had to port sslc to 64-bit.

To verify that the 64-bit version produces identical bytecode I set up a build pipeline for the Restoration Project, which compiles all the scripts with both architectures and compares their checksums:

@roginvs I know you did the linux port, so maybe you could have a look at whether this looks correct to you when you have time

Looks good for me.

In some places it is uint32_t and in some places it is int. Should we have unit32_t everywhere?

When I added wasm build I added tests to validate outcome on RPU scripts. We can also add the same test for 64bit build

[roginvs]

Yes, here is a fix for tests #23

(Note: https://github.com/BGforgeNet/VScode-BGforge-MLS/ should be able to compile using built-in sslc (wasm version) on every platform which supports vscode)

[JanSimek]

Added test pipeline for OS X as well as 64bit runs for linux and Windows, so hopefully this is done. Feel free to update the PR if you see anything else that could be improved.

In case it is of any use, I did a similar exercise last year: #19. I had more trouble getting it working than you did!
