Release v0.12.3

Fixed

• Added missing binary division operator so that things like this will now correctly parse.

  select CAST(4 / 9 AS DECIMAL(5,2)) as hat
  from pants;

• Fixed BETWEEN expression grammar to remove bad recursion.

  select num
  from nums n
  where num between 100 AND 200;

• Fixed ORDER BY grammar to allow more than two ordering expressions.

  select color, size, shape, name
  from eggs
  order by color asc, size desc, shape asc
