v0.8.3

Added

• Add new data type for datetimes with timezones: {:datetime, precision, time_zone}
  The old dtype is now {:naive_datetime, precision}.

• Add option to rechunk the dataframes when using Explorer.DataFrame.from_parquet/3

Changed

• Change the {:datetime, precision} dtype to {:naive_datetime, precision}.
  The idea is to mirror Elixir's datetime, and introduce support for time zones.
  Please note: {:datetime, precision} will work as an alias for {:naive_datetime, precision} for now but will raise a warning.
  The alias will be removed in a future release.

• Literal %NaiveDateTime{} structs used in expressions will now have :microsecond precision.
  Previously they defaulted to :nanosecond precision.
  This was incorrect because %NaiveDateTime{} structs only have :microsecond precision.

Fixed

• Fix regression in Explorer.DataFrame.concat_rows/2.
  It's possible to concat dataframes that are not aligned again.

• Fix "is_finite" and "is_infinite" from Series to work in the context of a Explorer.Query.
