Setup binarywatch.org to check our packaged binaries

[notmandatory]

Describe the enhancement

Since we are producing binaries for our language bindings packages (Kotlin, Swift, Python) we should setup signed reproduceable builds for them. And then have binary watch verify the binaries match the versions we've signed.

https://binarywatch.org/about.html

Use case

Verify the integrity of our binary packages.
