--description--

Given an array of hours worked today per person, return the number of pizzas to order for a pizza party.

• Divide each person's hours worked by 3 to get their slice count.
• You can't eat a partial slice, so round each person's slice count up to the nearest whole number.
• Each person gets a minimum of two slices.
• Each pizza has 8 slices. Round the total number of pizzas up to the nearest whole pizza.

get_pizzas_to_order([8, 8, 8]) should return 2.
