Function patch_seq_roll 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_roll(stack: Stack) -> Stack

Roll: Rotate n+1 items, bringing the item at depth n to the top ( x_n x_(n-1) … x_1 x_0 n – x_(n-1) … x_1 x_0 x_n )

Safety

Stack must have at least n+1 values (plus the index value).

Panics

• If the top value is not an Int
• If n is negative
• If n exceeds the current stack depth
