Log only dirty fields, but force log specific fields even though it's not dirty

[bayukartiko]

Firstly, thank you for this awesome package that has helped me in my current application!

I have received a report from one of my users stating that the logs that were only dirty did not provide the changed data 'code'.
Currently, the code in my model looks like this:

public function getActivitylogOptions(): LogOptions
{
    return LogOptions::defaults()
    ->logOnly(['code', 'name', 'type'])
    ->logOnlyDirty()
    ->forceLogEvenIfNotDirty(["code"]); // <-- this is new feature idea
}

I believe that this will solve the problem reported by my user and that some people may have been looking for this feature. Would be nice to have that feature
