Support for cube

[roji]

Once npgsql/npgsql#698 is implemented at the ADO level, we can expose support for this at the EF level as well.

Any chance of this making it in soon? Or are there decent workarounds for interacting with cubes that already exist?

@keyneom some work was done by a contributor at the ADO.NET level (npgsql/npgsql#3867) but was never completed. We haven't seen many users interested in this, so it hasn't been prioritized much...

It looks like the updates there have been made, is there a breakdown of what work would need to be completed on the efcore.pg side to get Cube properly supported here? I'd be interested in helping get that completed with a little direction on how to approach it
