Roadmap (Writer)

a. New log file at day start

b. New log file when file reaches x Mb

c. Old log file is zipped

d. satisfy Fiber interface below

// WithLogger is a logger interface that output logs with a message and key-value pairs.
type WithLogger interface {
	Tracew(msg string, keysAndValues ...any)
	Debugw(msg string, keysAndValues ...any)
	Infow(msg string, keysAndValues ...any)
	Warnw(msg string, keysAndValues ...any)
	Errorw(msg string, keysAndValues ...any)
	Fatalw(msg string, keysAndValues ...any)
	Panicw(msg string, keysAndValues ...any)
}
