fix Perlin augmenter for non divisible image sizes

[djdameln]

Description

• Perlin noise augmentation for DRAEM was instable for image sizes that were not a power of 2. This PR adds a quick fix for this issue by generating the Perlin noise mask with a dimensionality equal to the nearest power of 2 and then cropping back to the original image size.
• This temporarily fixes the issues with DRAEM until we create our own implementation of Perlin noise.
