Addresses #211

@hslzr hey, this one is going to be really tricky to get right as the types themselves may need to be transposed — especially if they are tuples. I’m going to close this PR and work on it in a new branch. For example:

If you have a

Literal::Array(
  Literal::Tuple(
    String,
    Integer
  )
)

then #transpose should return a

Literal::Tuple(
  Literal::Array(String),
  Literal::Array(Integer)
)
