Mac binaries are reported damaged under Catalina

Running under Catalina macOS 10.15.7, for all the Mac binaries I've tried to download, 1.5.4, 1.5.3, 1.5.2, when I double click on the resultant Yamcs Studio app, I get a report that the app is damaged. See attached

Ok apparently this can happen under macOS, but it would be nice if the app had an installer to fix the issue.
Anywho, after some poking around osxdaily, I found a series of workarounds. But only this one succeeded:
Assuming that you placed the Yamcs Studio.app file in the /Applications folder, you can issue the following Terminal command to coax it into becoming a runnable app:
xattr -cr "/Applications/Yamcs Studio.app"
After this I was able to start the app without issue.

It's coming from Gatekeeper, which added lots of (annoying) checks over the years.
This solution, similar to yours, is what works for me (Big Sur): sudo xattr -rds com.apple.quarantine ~/Downloads/Yamcs\ Studio.app

I think the only way to avoid the issue, is for us to buy a Developer ID from Apple, and going through the signing/notary process upon each release.Since Apple Developer IDs are not exactly free, and the workaround is 'reasonable', I would rather avoid buying a Developer ID for now.

But I will add a note in README with this information.
