isCartwrightSturmfels w
Given a permutation in 1-line notation, checks if the permutation is Cartwright-Sturmfels. By [CDG22], the matrix Schubert variety $X_w$ is Cartwright-Sturmfels if and only if $w$ avoids all of the patterns $\{12543, 13254, 13524, 13542, 21543, 125364, 125634, 215364, 215634, 315264, 315624, 315642\}$.
