Title: Free GPU mem after cudaPadding

Projections as input images are not needed in GPU after padding.

To discuss:
GPU memory is scarce resource so it is recommended to release any unnecessary buffer immediately.
But this implementation needs to modify CudaDataManager. Please see if this scenario is acceptable or if you have better proposal.
