Function to keep rolling when point is established
Let us code the function that will handle all rolling that occurs after a point has been established. Recall that this means it should continue rolling until either the point is rolled again, or a 7 is rolled. Once either of these happens, it should stop, and report back whether the result is a win or a loss.
Note that within this function, we will again use the roll_dice function that we previously defined.

Exercise instructions
- Fill in the conditions in the while loop to continue rolling until either a 7 or the point is rolled.
- Fill in the condition to check if the most recent roll will result in a win.

roll_after_point <- function(point){
new_roll <- 0
# Roll until either a 7 or the point is rolled
while( ___ ){
new_roll <- roll_dice(2)
if(new_roll == 7){
won <- FALSE
}
# Check whether the new roll gives a win
if(___ == ___){
won <- TRUE
}
}
return(won)
