The sequence/choice nodes in the Pest grammar AST are binary. We should allow them to flatten such that:

(choice
  (choice
    (identifier "a")
    (identifier "b")
  )
  (identifier "c")
)

Turn into:

(choice
  (identifier "a")
  (identifier "b")
  (identifier "c")
)

This makes downstream consumption easier. Note that sequence has higher precedence than choice.

Flattens the choice operator

Need to refactor this to be a bit more generic so we can re-use logic
for `sequence` operator

Towards partiql#37.

Implements a `flatten` a higher-order function to operate on binary
operators that have associativity like `choice`/`sequence`.

Resolves partiql#37.
