All image iterators

- Added tif/tiff as valid image formats.

DataFrameIterator

- Removed value `"other"` for `class_mode` argument in `image.DataFrameIterator`; added values `"raw"` and `"multi_output"` (and in `ImageDataGenerator.flow_from_dataframe`)..
- Added argument `weight_col` in `image. DataFrameIterator` (and in `ImageDataGenerator.flow_from_dataframe`).
- Removed argument `drop_duplicates` `image.DataFrameIterator` (and in `ImageDataGenerator.flow_from_dataframe`).
- Added argument `validate_filenames` in `image.DataFrameIterator` (and in `ImageDataGenerator.flow_from_dataframe`).

Bugfix release.

This is a bugfix release, removing an import that caused issues. See [prior changelog](https://github.com/keras-team/keras-preprocessing/releases/tag/1.0.6).

Remove an import that would cause a failure if pandas is not installed.

Changelog

- In `flow_from_dataframe`, `has_ext` is now deprecated.
- In `DataframeIterator`, `sort` is now deprecated.
- `flow_from_dataframe` now supports absolute paths.
- Most transformations now support an `order` parameters which can be used to determine the interpolation following PIL standard. The default is using `nearest`, which was the default before this addition.
