cicwi/PyCorrectedEmissionCT: Release version 0.5.0

New major release, adding the following features and fixing the following bugs: Added New module called models: VolumeGeometry: description of the volume. ProjectionGeometry: description / manipulation of the projection geometry. Support for unmatched pixel-voxel size, cone beam geometry, uneven volume shape. Arbitrary geometry, including tilted detector. Convolution operator and deconvolution support. Support for rotating projection stack. Support for computing cross-correlation curves. Computation of PSF for pencil beam scanning with gaussian beam. Support for computing attenuation maps outside the corrected projector. ### Fixed Pixel weights, when having small outliers. Volume mask generation Dimension bug in azimuthal integration. Inconsistency between astra-toolbox and scikit-image backends. ### Warning Some interfaces and some internal properties have been refactored / renamed
