This release adds image augmentation (brightness, contrast, hue, saturation) and four degree rotational augmentation.

Added parameters:

• --augment-rotate: Randomly rotates the training images by 0°, 90°, 180° or 270°.
• --augment-brightness (float): Randomly adjusts brightness of image. The value sets the standard deviation of a Gaussian distribution. The degree of augmentation is selected from this distribution. Default: 0.05
• --augment-contrast (float): Randomly adjusts contrast of image. The value sets the standard deviation of a Gaussian distribution. The degree of augmentation is selected from this distribution. Default: 0.05
• --augment-hue (float): Randomly adjusts hue of image. The value sets the standard deviation of a Gaussian distribution. The degree of augmentation is selected from this distribution. Default: 0.01
• --augment-saturation (float): Randomly adjusts saturation of image. The value sets the standard deviation of a Gaussian distribution. The degree of augmentation is selected from this distribution. Default: 0.05
• --regularization-l2 (float): Sets the L2 regularization of the optimizer. Default: 0.0001
