I updated this fork to

• remove the obsolete Python section (was removed before but snuck back in)
• update the Go target version.
• to do more than just 10 simple random tests. Go is fast, so it now has 1000 random tests (100 random alphabets and keys, each used to encode and decode 10 times).

You're confusing the log with the error message, the order is log first test result below, that test expects false. The previous one is the one expecting true.
