ZeroPC SourceKey logged for zero PC

The slog.Record.PC field can be loaded with a program counter (PC). This is normally done by the slog.Logger code. If the PC is non-zero and the slog.HandlerOptions.AddSource flag is set the source field will contain a slog.Source record containing the function name, file name, and file line at which the log record was generated. If the PC is zero then this field and its associated group should not be logged.

"- If r.PC is zero, ignore it."

Suggested

LevelCase Log level in lowercase

Each JSON log record contains the logging level of the log statement as a string. Different handlers provide that string in uppercase or lowercase. Documentation for slog.Level says that its String() and MarshalJSON() methods will return uppercase but UnmarshalJSON() will parse in a case-insensitive manner.

Chanchal Zap		'info'

Phsym Zerolog		'info'

Samber Logrus		'info'

Samber Zap		'info'

Samber Zerolog		'info'
