Introduce a new algorithm to manage the tone mapping handling of the IPU3. The initial algorithm is chosen to configure the gamma contrast curve which moves the implementation out of AWB for simplicity. As it is initialised with a default gamma value of 1.1, there is no need to use the default table at initialisation anymore. This demonstrates the way to use process() call when the EventStatReady comes in. The function calculates the LUT in the context of a frame, and when prepare() is called, the parameters are filled with the updated values. AGC is modified to take the new process interface into account.
