Add support for additional image transformations in pyradiomics

Thereby, only LoG, Wavelet and Original image types can be activated. That leaves seven other image transformations unavailable, such as exponential, logarithm, square etc… I know that a full array of image modifications can be achieved by using a Parameters file but such a file in YAML is extremely user-unfriendly for anyone who is not seasoned code developer.
