Changes Made

This PR includes the following changes:

• Added the SetTimestamp method to the Logger struct in gologger, which allows the user to enable or disable automatic timestamps for log messages, and to set the minimum level of log messages for which timestamps should be included.
• Updated the init() function to set the default maximum log level to LevelInfo, and added a timestamp option for the formatter and writer.

How to use

The package provides a DefaultLogger variable that can be used to log messages with different levels (Debug, Info, Error, etc.). You can configure the behavior of the DefaultLogger using various methods, such as SetTimestamp.

An example of how to use this package:

package main

import (
	"github.com/projectdiscovery/gologger"
)

func main() {
    gologger.DefaultLogger.SetTimestamp(true, levels.LevelDebug)
    gologger.Debug("This message will include a timestamp because its level is greater than or equal to LevelDebug")
}

This approach doesn't seem very scalable. Each new added instruction will require the .Timestamp() call. I think we should either define an helper function that will invoke:

gologger.Debug().Timestamp().Msgf("xxx)

or make this configurable via gologger itself, for example with global setter like:

gologger.EnableTimestamp()
gologger.EnableTimestampForLevel(Debug|Info|etc)

Also, I think that the timestamp should be disabled by default, as it can make the output easily unreadable (similarly to #2928)

Important note:
Before merging this PR, make sure that the PR (projectdiscovery/gologger#29) on the Logger has also been merged. The function called in this PR currently does not exist on the master branch of the Logger and would cause issues.

You can test with the specific gologger commit with:

go get -v github.com/projectdiscovery/gologger@1c357ca

[Mzack9999]

You might need to point gologger with the correct reference:

go get -v github.com/projectdiscovery/gologger@xxx
