Logging library does not export struct fields

[C-Deck]

The logging library used by this project does not export the struct members for the Field struct.

type Logger interface {
	DebugLogger
	InfoLogger
	WarnLogger
	ErrorLogger
	FatalLogger
	PanicLogger
	LevelLogger(level Level) LevelLogger
}

type DebugLogger interface {
	Debug(msg string,fields ...Field)
}

type Field struct {
	kind           FieldKind
	key            string
	stringValue    string
	stringsValue   []string
	intValue       int64
	byteValue      []byte
	interfaceValue interface{}
	errorValue     error
}

This blocks custom implementations of the interface even though the libraries documentation says custom implementations are possible. There is no way to access any fields provided to the custom implementation.
