Like dplyr_reconstruct.epi_df but not recomputing any grouping

Description

In the move to our current not-quite-proper/effective "implementation" of dplyr::dplyr_extending for epi_dfs, we moved a lot of checks in dplyr_reconstruct and used it instead of reclass() in various operations to prevent operations from outputting invalid metadata/classes, instead of more careful tailored and relevant checks. However, this actually introduced extra overhead due to dplyr_reconstruct.epi_df() passing off to dplyr_reconstruct.grouped_df() when grouped, which assumes that it will need to / should for safety recompute the groups, even when it'd be safe for it not to do so. In many operations, we're using NextMethod() to dispatch to grouped_df behavior if needed, and it should output something with valid groupings.

Usage

reconstruct_light_edf(data, template)

Details

This function serves the original purpose of performing epi_df-centric checks rather than just throwing on potentially-incorrect metadata like reclass(), but without unnecessary dplyr_reconstruct() delegation.
