LGTM, but need the current test results used for comparison updated. This is all in testing/.

If you need some help with this, let me know, I can get around to it eventually if you are busy.

Last commit should've now done this, please have a look and double check :)

Not blocking, but would be nice to convert it to SFA_FAST at some point, which is much faster.

Yeah, I did briefly look into doing this but ran into some numba weirdness so put it on the back burner for now.

I’ll make an issue like @TonyBagnall suggested.
