Surely there’s a better way to do this, but I’ve:

- unpacked `fluid.dataset~` / `fluid.labelset~` to `dict`s
- `dict.unpack data:` just to get the data bits
- `push_to_coll` to move into `coll`-land
- use the label `coll` to fork the MFCC `coll` into a separate `coll` per class
- `pull_from_coll` back into `dict`-land and `load` into `fluid.dataset~`s (one per class)
- `tobuffer` the `fluid.dataset~`s to get them into `buffer~`s
- `fluid.bufstats~` to get the means per column (now channels)
- `fluid.buf2list @axis 1` to get the mean of each class

What a journey!

I could probably skip the `coll` stuff and operate on the `dict` versions, I just know the `coll` syntax offhand so did stuff there. But it was quite a tour the `fluid.objects~` to do this!
