new interface for savedata probably breaks p1640

[Jason Wang]

I added a new required function argument to savedata to save klip parameters. Check out the new calls the savedata in parallelized.klip_dataset too see how the calling has changed. This means I've probably broken the p1640 interface...

Thanks, I'll make sure to incorporate this while I rewrite the P1640 instrument class.

P1640 class works, should have marked this resolved a long time ago
