[parser] ListParser can handle lists of more than 2 elements 😮
...
As ListParser sees items within its list, it assembles a vector of Pairs. When
the parser encounters ')', it assembles the pairs into an actual linked list and
returns the root Pair.
This work also revealed that I was asserting incorrectly in my single_pair test.
It should return Null instead of an empty Pair. Neat.
Closes #17 .
