This patch adds wrappers around the functions from package https://github.com/bethgelab/imagecorruptions. The functions in that package were used in some recent papers and are added here for convenience. The wrappers produce arrays containing values identical to the output arrays from the corresponding `imagecorruptions` functions when called via the `imagecorruptions.corrupt()` (verified via unittests). The interfaces of the wrapper functions are identical to the `imagecorruptions` functions, with the only difference of also supporting `seed` parameters. * Add module `imgaug.augmenters.imgcorruptlike`. The `like` signals that the augmentation functions do not *have* to wrap `imagecorruptions` internally. They merely have to produce the same outputs. * Add the following functions to module `imgaug.augmenters.imgcorruptlike`: * `apply_gaussian_noise()` * `apply_shot_noise()` * `apply_impulse_noise()` * `apply_speckle_noise()` * `apply_gaussian_blur()` * `apply_glass_blur()` (improved performance over original function) * `apply_defocus_blur()` * `apply_motion_blur()` * `apply_zoom_blur()` * `apply_fog()` * `apply_snow()` * `apply_spatter()` * `apply_contrast()` * `apply_brightness()` * `apply_saturate()` * `apply_jpeg_compression()` * `apply_pixelate()` * `apply_elastic_transform()` * Add function `imgaug.augmenters.imgcorruptlike.get_corruption_names(subset)`. Similar to `imagecorruptions.get_corruption_names(subset)`, but returns a tuple `(list of corruption method names, list of corruption method functions)`, instead of only the names. * Add the following augmenters to module `imgaug.augmenters.imgcorruptlike`: * `GaussianNoise` * `ShotNoise` * `ImpulseNoise` * `SpeckleNoise` * `GaussianBlur` * `GlassBlur` * `DefocusBlur` * `MotionBlur` * `ZoomBlur` * `Fog` * `Frost` * `Snow` * `Spatter` * `Contrast` * `Brightness` * `Saturate` * `JpegCompression` * `Pixelate` * `ElasticTransform` * Add context `imgaug.random.temporary_numpy_seed()`.

This patch adds wrappers around the functions from
package
https://github.com/bethgelab/imagecorruptions.
The functions in that package were used in some recent
papers and are added here for convenience.
The wrappers produce arrays containing values
identical to the output arrays from the corresponding
imagecorruptionsfunctions when called via theimagecorruptions.corrupt()(verified via unittests).The interfaces of the wrapper functions are identical to the
imagecorruptionsfunctions, with the only difference ofalso supporting
seedparameters.imgaug.augmenters.imgcorruptlike.The
likesignals that the augmentation functions donot have to wrap
imagecorruptionsinternally.They merely have to produce the same outputs.

imagecorruptions.get_corruption_names(subset),but returns a tuple
(list of corruption method names, list of corruption method functions),instead of only the names.
