Paganin's filter is corrected according to the equation in the original paper.
Frequency domain is normalized to the value of 2*pi instead of original value of 0.5.
When padding is set to False, the result was giving constant value on the image. Therefore the code is changed accordingly.
Minus logarithm is added according to the Paganin's filter equation. (The place of the minus logarithm could also be in the filter itself).

Closes #474 Related to #500

Thanks @Arhatari for this PR! This has been brought up several times before, but never had the chance to do it properly.

However, because there are many users that may have used and become familiar with the parameter settings of the "current" filter, I suggest we name the new function as retrieve_phase_paganin so that some of the users want to continue using their old function. We may need to update the documentation and say which what each function actually does. What do you say?
