Case contract

Input [cards_in_current_count, new_card]. Values A=1, T/J/Q/K=10; a count above 31 is "illegal". Points: count 15 -> 2, count 31 -> 2; the new card with the immediately preceding same-rank run scores 2/6/12; the longest trailing sequence of 3+ cards whose ranks are consecutive in any order scores its length. Return [points, count].
