Scott Sanderson 8220d1ee86 ENH: Adds support for different typed adjusted arrays and adds an 
EarningsCalendar loader.

- Moves most of AdjustedArray back into Python. The window iterator is
  the only part that's performance-intensive.

- Adds a bootleg templating system for creating specialized versions of
  AdjustedArrayWindow for each concrete type we care about.

- Adds support for differently dtyped terms in pipeline. This allows us
  to use datetime64s which are needed in the EarningsCalendar.

- Adds EarningsCalendar dataset for the next and previous earnings
  announcements in pipeline.

- Adds in memory loader for EarningsCalendar.

- Adds blaze loader for EarningsCalendar.
