This uses the original version of reductions with an additional statement on the dataset methods that adds the original coordinates back in.
Using apply_ufunc and np.cumsum/cumprod has some issues as it only finds the cumulative across one axis which makes iterating through each dimension necessary. This makes it slower than the original functions and also causes some problems with the groupby method.
Happy for any input on how the method using apply_ufunc might be usable or on any ways to change the current method.
I'm getting a few issues I don't quite understand:
- When running pytest on my local repository I get no errors but it's failing the checks here with a NotImplementedError
- Black is having an issue with some of the strings in generate_aggregations. It's saying it cannot parse what should be valid code.
Thanks!

I'm running into an issue with variables without the core dimensions. Would it be better to do a work around in cumsum or in apply_unfunc like you mentioned in #6391

I'll try to work that in.

This is what I initially had but I thought it might be confusing for users passing something to missing_dims
