[Feature Request] Add shape, ndim and dtype properties to slicerator object

[rockandsalt]

I would like to process slicerator object in chunks using dask. Dask has the following function ( link) . That can convert array like object to their object type but it needs to have the shape, ndim and dtype properties implemented.

This feature seems trivial to implement. I can do a pull a request in the future. But, I would like to know if you have any input on that.
