Can you explain what SupervisorJob is in the context of coroutines and task management in Kotlin?

SupervisorJob is a special type of Job in Kotlin Coroutines used to manage a group of coroutines, where an error in one coroutine does not cancel the others.

In a regular Job (or CoroutineScope), if an exception occurs in one child coroutine, all other child coroutines are canceled. With SupervisorJob, this behavior changes: an error in one coroutine does not affect the execution of others.

Example of usage:

val supervisor = SupervisorJob()
val scope = CoroutineScope(Dispatchers.Default + supervisor)

scope.launch {
    // Coroutine that might fail
}

scope.launch {
    // Another coroutine that will continue to work even if the first fails
}

This is useful when you need to run several independent tasks in parallel without stopping all of them if one fails.
