[BUG] break and continue don't work as expected

[Akram Izzeldin]

Describe the bug
break and continue don't work if they are not direct children of the for loop body AST

To Reproduce
Steps to reproduce the behavior:
1- Run the following birb program

for (int j = 0; j < 5; j++) {
    if (j == 2) {
        break;
    }
    screm(j);
}

for (int k = 0; k < 5; k++) {
    if (k == 3) {
        continue;
    }
    screm(k);
}

Actual Results
first loop outputs 0 1 2 3 4
second loop outputs 0 1 2 3 4

Expected behavior
The first loop should output 0 1
The second loop should output 0 1 2 4

Additional context
The way this should be handled is by throwing an exception in visitBreak and visitContinue. The exception should be caught and handled by the loops (for and while). These exceptions aren't an indication of an error, but rather used as a flow control to unwind the call stack to the loops handling functions.
