Research direction
Start by reviewing the linked tidyr:::unnest documentation and the Stack Overflow and blog examples to understand the requested behavior. Check whether data.table already has a canonical approach; done would require an agreed API and efficient unnest behavior, but this issue does not name files or tests.
Written by the indexing model from the issue text.
Description
Similarly to tidyr:::unnest data.table would benefits from a fast unnest function.
