Allowing extraction of components of the drag kernel

[aprilnovak]

For fluid-structure interaction use cases, I'd like to have the option to compute the x/y/z components of the viscous drag. But currently, the drag kernel returns the magnitude of the drag:

s_sum[t] += sqrt(dragx * dragx + dragy * dragy + dragz * dragz);

Would a PR be accepted that allows someone to isolate these components instead of taking the vector sum? Thanks.

No need for a PR — this will be available in v25. We are currently working on preparing the v25-pre release.
