Add support for forward mode differentiation

1

Currently the custom VJP implementation is restricting the code to reverse mode differentiation. Though this is by far the more common of the two modes, we should add support for...

Users may like to downsample a signal consistently, which is most straightforward in harmonic space. This may involve starting from a high resolution pixel-space map, computing harmonic coefficients and then...
