Fix race conditions in logging package functions

The logging package contains two functions, SetLogOptions and SetLogFile, that could experience race conditions when multiple goroutines access and modify the logger struct concurrently. 
To address these issues, a copy of the logger struct is now created in each function to eliminate data races.

In addition, the test-go.sh script is updated to include the '-race' flag, enabling race detection during testing. This change helps prevent future race conditions by activating the Go race detector.
