Increase debug logging with function,file and linenumber (#1147)

Show the function name,file and linenumber like this
[0000]  INFO main:         [setupLogger:matterbridge.go:100] Enabling debug logging.
[0000]  INFO main:         [main:matterbridge.go:46] Running version 1.17.5-dev

Only enable this for debug as this adds some overhead.
