Implement Spoonbill-like table improvements

[jpmckinney]

Flatterer has some options like:

• pushdown=["ocid", ...]
• inline_one_to_one=True
• schema="path" (column order)

[yolile]

We could also offer the sqlite export option, which saves external advanced analysts/users some steps

[jpmckinney]

Has anyone requested SQLite?

[yolile]

Not yet, but I though it could be useful for us in case we want to start creating notebooks to calculate indicators with data from the registry for external users. For example, MAPS, or SPP related ones.

[jpmckinney]

Sounds good. I created #387 since this issue can be closed without doing SQLite.
