https://github.com/CERN/TIGRE/pull/376 introduced offset weighting for lots of reconstruction algorithms, and tidied up the offset weighting code, but in doing so removed control of the weighting in FDK. In its current state, the decision on whether to do the weighting is made automatically.
In this PR I added the control back in, so the user can turn the weights on/off using the 'wang' input, as before. The default is true. I also removed theta from zeropadding and inputs proj and geo from parse_inputs, because they are no longer used.
A question remains about lines 47-48: % Zero-padding to avoid FFT-induced aliasing %TODO: should't this be for all cases, not just wang?. I don't know the answer to this.
