This function serves as a handler for the different implementations of the IUWT decomposition. It allows the
    different methods to be used almost interchangeably.

    INPUTS:
    in1                 (no default):       Array on which the decomposition is to be performed.
    scale_count         (no default):       Maximum scale to be considered.
    scale_adjust        (default=0):        Adjustment to scale value if first scales are of no interest.
    mode                (default='ser'):    Implementation of the IUWT to be used - 'ser', 'mp' or 'gpu'.
    core_count          (default=1):        Additional option for multiprocessing - specifies core count.
    store_smoothed      (default=False):    Boolean specifier for whether the smoothed image is stored or not.
    store_on_gpu        (default=False):    Boolean specifier for whether the decomposition is stored on the gpu or not.

    OUTPUTS:
    Returns the decomposition with the additional smoothed coefficients if specified.
