Scott Sanderson bc302beec9 MAINT: Rework event datasets.
- Refactored EventsLoader and BlazeEventsLoader to not require a
  subclass per dataset.  Instead, you now pass a map from columns to
  event fields directly to the EventsLoader constructor.

- Removed a large number of Quantopian-specific datasets and associated
  tests.

- Rewrote the core logic of EventsLoader and BlazeEventsLoader to share
  index calculations across multiple requested columns.

- Fixed a bug where event fields were incorrectly forward-filled when
  null values were present in an event.

Scott Sandersonandllllllllll 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.
