Optimize and

[ryanve]

Simplify operation needed for ssv.and while still reusing existing code. I chose the middle way after sampling 3 ways in node 12 with lap

366 ops/ms

// original way
return not(
  or(left, left),
  xor(left, right))

458 ops/ms

// faster and terser
return not(
  yolo(left),
  xor(left, right))

545 ops/ms

// fastest but trippy
return not(
  yolo(left),
  not(left, right) + space +
  not(right, left))

sample operation

ssv.and("mark tom travis", "tom scott travis")
