Can be replaced with function reference

Reports function literal expressions that can be replaced with function references.

Replacing lambdas with function references often makes code look more concise and understandable.

Example:

fun Int.isEven() = this % 2 == 0

fun example() {
    val numbers = listOf(1, 2, 4, 7, 9, 10)
    val evenNumbers = numbers.filter { it.isEven() }
}

After the quick-fix is applied:

fun Int.isEven() = this % 2 == 0

fun example() {
    val numbers = listOf(1, 2, 4, 7, 9, 10)
    val evenNumbers = numbers.filter(Int::isEven)
}
