`Tuple1SemigroupalOps` methods have different names from other `TupleNSemigroupalOps` classes

[m50d]

I don't know whether this is a deliberate design decision, but it seems wrong to me: the TupleNSemigroupalOps classes offer a consistent family of methods like mapN and traverseN, but for Tuple1SemigroupalOps these get generated as map and traverse instead. I'd like to be able to work consistently with tuples of any size, including 1, so I think it would make more sense if Tuple1SemigroupalOps (and friends) generated the same mapN/traverseN/etc. methods that are present on all the other TupleNSemigroupalOps classes.
